How Do I Study Geography? • Everything you see, touch, use, and even hear is related to geography–the study of the world’s people, places, and environments. • How can you possibly study such a huge amount of information in your geography class? Where do you start? (pages 2–3) Click the mouse button or press the Space Bar to display the information. How Do I Study Geography? (cont.) • Geographers–people who study geography–ask themselves this question, too. • To understand how our world is connected, some geographers have broken down the study of geography into five themes. • The Five Themes of Geography are (1) location, (2) place, (3) human/ environment interaction, (4) movement, and (5) regions. (pages 2–3) Click the mouse button or press the Space Bar to display the information. How Do I Study Geography? (cont.) • Most recently, as suggested in the Geography Standards for Life, geographers have begun to look at geography a different way. • They break down the study of geography into Six Essential Elements, which are explained for you on the following slides. • Being aware of these elements will help you sort out what you are learning about geography. (pages 2–3) Click the mouse button or press the Space Bar to display the information. Element 1: The World in Spatial Terms • Geographers first take a look at where a place is located. • Location serves as a starting point by asking “Where is it?” • Knowing the location of places helps you to orient yourself in space and to develop an awareness of the world around you. (pages 2–3) Click the mouse button or press the Space Bar to display the information. Element 2: Places and Regions • Geographers also look at places and regions. • Place includes those features and characteristics that give an area its own identity or personality. • These can be physical characteristics– such as landforms, climate, plants, and animals–or human characteristics–such as language, religion, architecture, music, politics, and way of life. (pages 2–3) Click the mouse button or press the Space Bar to display the information. Element 2: Places and Regions (cont.) • To make sense of all the complex things in the world, geographers often group places or areas into regions. • Regions are united by one or more common characteristics. (pages 2–3) Click the mouse button or press the Space Bar to display the information. Element 3: Physical Systems • Why do some places have mountains and other places have flat deserts? • When studying places and regions, geographers analyze how physical systems–such as volcanoes, glaciers, and hurricanes–interact and shape the earth’s surface. • They also look at ecosystems, or communities of plants and animals that are dependent upon one another and their particular surroundings for survival. (pages 2–3) Click the mouse button or press the Space Bar to display the information. Element 4: Human Systems • Geographers also examine human systems, or how people have shaped our world. • They look at how boundary lines are determined and analyze why people settle in certain places and not in others. • An ongoing theme in geography is the continual movement of people, ideas, and goods. Click the mouse button or press the Space Bar to display the information. (pages 2–3) Element 5: Environment and Society • The study of geography includes looking at human/environment interaction, or how and why people change their surroundings. • Throughout history, people have cut forests and dammed rivers to build farms and cities. • Some activities have led to air and water pollution. (pages 2–3) Click the mouse button or press the Space Bar to display the information. Element 5: Environment and Society (cont.) • The physical environment affects human activities as well. • The type of soil and amount of water in a place determines if crops can be grown. • Earthquakes and floods also affect human life. (pages 2–3) Click the mouse button or press the Space Bar to display the information. Element 6: The Uses of Geography • Understanding geography, and knowing how to use the tools and technology available to study it, prepares you for life in our modern society. • Individuals, businesses, and governments use geography and maps of all kinds on a daily basis. • Computer programs, such as geographic information systems (GIS), allow us to make informed decisions about how to make the best use of our (pages 2–3) place and region. Click the mouse button or press the Space Bar to display the information. Guide to Reading Main Idea Globes and maps provide different ways of showing features of the earth. Terms to Know • hemisphere • scale • latitude • relief • longitude • elevation • scale bar • contour line Click the mouse button or press the Space Bar to display the information. Guide to Reading (cont.) Section Objectives • Explain how to find an exact location. • Understand how maps are made. • Explain how to recognize the special parts of a map. • Describe how to identify different kinds of maps. Click the mouse button or press the Space Bar to display the information. What is a Globe? • A globe is a model of the earth that shows the earth’s shape, lands, distances, and directions as they truly relate to one another. • A world globe can help you find your way around the earth. By using one, you can locate places and determine distances. (page 4) Click the mouse button or press the Space Bar to display the information. Hemispheres • To locate places on the earth, geographers use a system of imaginary lines that crisscross the globe. • One of these lines, the Equator, circles the middle of the earth like a belt. • It divides the earth into “half spheres,” or hemispheres. • Everything north of the Equator is in the Northern Hemisphere. • Everything south of the Equator is in the Southern Hemisphere. (pages 4–5) Click the mouse button or press the Space Bar to display the information. Hemispheres (cont.) • Another imaginary line runs from north to south. • It helps divide the earth into half spheres in the other direction. • Find this line–called the Prime Meridian or the Meridian of Greenwich–on a globe. • Everything east of the Prime Meridian for 180 degrees is in the Eastern Hemisphere. (pages 4–5) Click the mouse button or press the Space Bar to display the information. Hemispheres (cont.) • Everything west of the Prime Meridian for 180 degrees is in the Western Hemisphere. • In which hemispheres is North America located? It is found in both the Northern Hemisphere and the Western Hemisphere. Click the mouse button or press the Space Bar to display the information. Hemispheres (cont.) Latitude and Longitude • The Equator and the Prime Meridian are the starting points for two sets of lines used to find any location. • Parallels circle the earth like stacked rings and show latitude, or distance measured in degrees north and south of the Equator. • The letter N or S following the degree symbol tells you if the location is north or south of the Equator. (pages 5–6) Click the mouse button or press the Space Bar to display the information. Latitude and Longitude (cont.) • The North Pole, for example, is at 90°N (North) latitude, and the South Pole is at 90°S (South) latitude. • Two important parallels in between the poles are the Tropic of Cancer at 23½°N latitude and the Tropic of Capricorn at 23½°S latitude. • You can also find the Arctic Circle at 66½°N latitude and the Antarctic Circle at 66½°S latitude. (pages 5–6) Click the mouse button or press the Space Bar to display the information. Latitude and Longitude (cont.) • Meridians run from pole to pole and crisscross parallels. • Meridians signify longitude, or distance measured in degrees east (E) or west (W) of the Prime Meridian. • The Prime Meridian, or 0° longitude, runs through Greenwich, England. • On the opposite side of the earth is the 180° meridian, also called the International Date Line. (pages 5–6) Click the mouse button or press the Space Bar to display the information. Latitude and Longitude (cont.) • Lines of latitude and longitude cross each other in the form of a grid system. • You can find a place’s absolute location by naming the latitude and longitude lines that cross exactly at that place. • For example, the city of Tokyo, Japan, is located at 36°N latitude and 140°E longitude. (pages 5–6) Click the mouse button or press the Space Bar to display the information. Latitude and Longitude (cont.) How Maps Are Made • For more than 4,000 years, people have made maps to organize their knowledge of the world. • The reason for producing maps has not changed over the centuries, but the tools of mapmaking have. • Today satellites located thousands of miles in space gather data about the earth below. (page 6) Click the mouse button or press the Space Bar to display the information. How Maps Are Made (cont.) • The data are then sent back to the earth, where computers change the data into images of the earth’s surface. • Mapmakers analyze and use these images to produce maps. • For modern mapmakers, computers have replaced pen and paper. • Most mapmakers use computers with software programs called geographic information systems (GIS). (page 6) Click the mouse button or press the Space Bar to display the information. How Maps Are Made (cont.) • With GIS, each kind of information on a map is kept as a separate electronic “layer” in the map’s computer files. • Because of this modern technology, mapmakers are able to make maps– and change them–more quickly and easily than before. (page 6) Click the mouse button or press the Space Bar to display the information. How to Read a Map • Maps can direct you down the street, across the country, or around the world. • An ordinary map holds all kinds of information. • Learn the map’s code, and you can read it like a book. (pages 6–7) Click the mouse button or press the Space Bar to display the information. How to Read a Map (cont.) • Map Key The map key explains the lines, symbols, and colors used on a map. • Look at the map of Spain on the following slide. (pages 6–7) Click the mouse button or press the Space Bar to display the information. How to Read a Map (cont.) (pages 6–7) How to Read a Map (cont.) • Its key shows that dots mark major cities. • A circled star indicates the national capital–in Spain’s case, the city of Madrid. • Some keys tell which lines stand for national boundaries, roads, or railroads. • Other map symbols may represent human-made or natural features, such as canals, forests, or natural gas deposits. (pages 6–7) Click the mouse button or press the Space Bar to display the information. How to Read a Map (cont.) • Compass Rose An important step in reading any map is to find the direction marker. • A map has a symbol that tells you where the cardinal directions–North, South, East, and West–are positioned. • Sometimes all of these directions are shown with a compass rose. (pages 6–7) Click the mouse button or press the Space Bar to display the information. How to Read a Map (cont.) • An intermediate direction, such as southeast, may also be on the compass rose. • Intermediate directions fall between the cardinal directions. (pages 6–7) Click the mouse button or press the Space Bar to display the information. How to Read a Map (cont.) • Latitude and Longitude Lines Like globes, maps have lines of latitude and longitude that form a grid. • Every place on the earth has a unique position or “address” on this grid. • Knowing this address makes it easier for you to locate cities and other places on a map. (pages 6–7) Click the mouse button or press the Space Bar to display the information. How to Read a Map (cont.) • For example, what is the grid address of Madrid, Spain? • The map below shows you that the address is 41°N latitude, 4°W longitude. (pages 6–7) Click the mouse button or press the Space Bar to display the information. How to Read a Map (cont.) • Scale A measuring line, often called a scale bar, helps you determine distance on a map. • The map’s scale tells you what distance on the earth is represented by the measurement on the scale bar. • For example, 200 miles on the earth may be represented by 1 inch on the map. (pages 6–7) Click the mouse button or press the Space Bar to display the information. How to Read a Map (cont.) • Knowing the scale allows you to see how large an area is. • Map scale is usually given in both miles and kilometers. • Each map has its own scale. • What scale a mapmaker uses depends on the size of the area shown on the map. (pages 6–7) Click the mouse button or press the Space Bar to display the information. How to Read a Map (cont.) • If you were drawing a map of your backyard, you might use a scale of 1 inch equals 5 feet. • In contrast, the scale bar on the map of Austin, Texas, on the following slide, shows that about ¼ inch represents 8 miles. • Scale is important when you are trying to compare the size of one area to another. (pages 6–7) Click the mouse button or press the Space Bar to display the information. How to Read a Map (cont.) (pages 6–7) General Purpose Maps • Maps are amazingly useful tools. • You can use them to preserve information, to display data, and to make connections between seemingly unrelated things. • Geographers use many different types of maps. • Maps that show a wide range of general information about an area are called general purpose maps. (pages 7–8) Click the mouse button or press the Space Bar to display the information. General Purpose Maps (cont.) • Two of the most common general purpose maps are political and physical maps. • Political Maps Political maps show the names and boundaries of countries and identify only major physical features. • The political map of Spain on the following slide, for example, shows the boundaries between Spain and other countries. It also shows cities and rivers within Spain and bodies of water surrounding Spain. (pages 7–8) Click the mouse button or press the Space Bar to display the information. General Purpose Maps (cont.) (pages 7–8) General Purpose Maps (cont.) • Physical Maps Physical maps call out landforms and water features. • The physical map of Sri Lanka on the following slide shows rivers and mountains. (pages 7–8) Click the mouse button or press the Space Bar to display the information. General Purpose Maps (cont.) (pages 7–8) General Purpose Maps (cont.) • The colors used on physical maps include brown or green for land, and blue for water. • These colors and shadings may show relief–or how flat or rugged the land surface is. • In addition, physical maps may use colors to show elevation–the height of an area above sea level. • A key explains what each color and symbol stands for. (pages 7–8) Click the mouse button or press the Space Bar to display the information. General Purpose Maps (cont.) • Contour Maps One kind of physical map, called a contour map, also shows elevation. • A contour map has contour lines–one line for each major level of elevation. • All the land at the same elevation is connected by a line. • These lines usually form circles or ovals–one inside the other. (pages 7–8) Click the mouse button or press the Space Bar to display the information. General Purpose Maps (cont.) • If contour lines come very close together, the surface is steep. • If the lines are spread apart, the land is flat or rises very gradually. • Compare the contour map of Sri Lanka to its physical map. (pages 7–8) Click the mouse button or press the Space Bar to display the information. Special Purpose Maps • Some maps are made to present specific kinds of information. • These are called thematic or special purpose maps. • They usually show themes or patterns, often emphasizing one subject or theme. • Special purpose maps may present climate, natural resources, and population density. (pages 8–9) Click the mouse button or press the Space Bar to display the information. Special Purpose Maps (cont.) • They may also display historical information, such as battles or territorial changes. • The map’s title tells what kind of special information it shows. • Colors and symbols in the map key are especially important on these types of maps. (pages 8–9) Click the mouse button or press the Space Bar to display the information. Special Purpose Maps (cont.) • One type of special purpose map uses colors to show population density, or the average number of people living in a square mile or square kilometer. • As with other maps, it is important to first read the title and the key. • The population density map of Egypt on the following slide gives a striking picture of differences in population density. (pages 8–9) Click the mouse button or press the Space Bar to display the information. Special Purpose Maps (cont.) (pages 8–9) Special Purpose Maps (cont.) • The Nile River valley and delta are very densely populated. • In contrast, the desert areas east and west of the river are home to few people.

What Is a Graph? • A graph is a way of summarizing and presenting information visually. • Each part of a graph gives useful information. • First read the graph’s title to find out its subject. • Then read the labels along the graph’s axes–the vertical line along the left side of the graph and the horizontal line along the bottom of the graph. (page 10) Click the mouse button or press the Space Bar to display the information. What Is a Graph? (cont.) • One axis will tell you what is being measured. • The other axis tells what units of measurement are being used. (page 10) Click the mouse button or press the Space Bar to display the information. Bar, Line, and Circle Graphs • Bar Graphs Graphs that use bars or wide lines to compare data visually are called bar graphs. • Look carefully at the bar graph on the following slide, which compares world languages. (pages 10–11) Click the mouse button or press the Space Bar to display the information. Bar, Line, and Circle Graphs (cont.) (pages 10–11) Bar, Line, and Circle Graphs (cont.) • The vertical axis lists the languages. • The horizontal axis gives speakers of the language in millions. • By comparing the lengths of the bars, you can quickly tell which language is spoken by the most people. • Bar graphs are especially useful for comparing quantities, and they may show the bars rising up from the bottom of the graph or extending out from the vertical axis. (pages 10–11) Click the mouse button or press the Space Bar to display the information. Bar, Line, and Circle Graphs (cont.) • Line Graphs A line graph is a useful tool for showing changes over a period of time. • The amounts being measured are plotted on the grid above each year, and then are connected by a line. • Line graphs sometimes have two or more lines plotted on them. • The line graph on the following slide shows that the number of farms in the United States has decreased since 1940. (pages 10–11) Click the mouse button or press the Space Bar to display the information. Bar, Line, and Circle Graphs (cont.) (pages 10–11) Bar, Line, and Circle Graphs (cont.) • The vertical axis lists the number of farms in millions. • The horizontal axis shows the passage of time in ten-year periods from 1940 to 1998. (pages 10–11) Click the mouse button or press the Space Bar to display the information. Bar, Line, and Circle Graphs (cont.) • Circle Graphs You can use circle graphs when you want to show how the whole of something is divided into its parts. • Because of their shape, circle graphs are often called pie graphs. • Each “slice” represents a part or percentage of the whole “pie.” • On the circle graph on the following slide, the whole circle (100 percent) represents the world’s population in (pages 10–11) 2000. Click the mouse button or press the Space Bar to display the information. Bar, Line, and Circle Graphs (cont.)

(pages 10–11) Charts • Charts present related facts and numbers in an organized way. • They arrange data, especially numbers, in rows and columns for easy reference. • Look at the chart on the following slide. (page 11) Click the mouse button or press the Space Bar to display the information. Charts (cont.) (page 11) Charts (cont.) • To interpret the chart, first read the title. • It tells you what information the chart contains. • Next, read the labels at the top of each column and on the left side of the chart. • They explain what the numbers or data on the chart are measuring. • One kind of chart, a flowchart, joins certain elements of a chart and a diagram. (page 11) Click the mouse button or press the Space Bar to display the information. Charts (cont.) • It can show the order of how things happen or how they are related to each other. • The flowchart on the following slide presents the branches of the United States government. (page 11) Click the mouse button or press the Space Bar to display the information. Charts (cont.) (page 11) Charts (cont.) • Notice how the chart shows the relationship among the tasks and the offices or bodies of each branch. (page 11) Pictograph • Like bar and circle graphs, pictographs are good for making comparisons. • Pictographs use rows of small pictures or symbols, with each picture or symbol representing an amount. • The pictograph on the following slide shows the number of automobiles produced in the world’s five major automobile-producing countries. (page 12) Click the mouse button or press the Space Bar to display the information. Pictographs (cont.) (page 12) Pictographs (cont.) • The key tells you that one car symbol stands for 1 million automobiles. • Pictographs are read like a bar graph. • The total number of car symbols in a row adds up to the auto production in each selected country. (page 12) Click the mouse button or press the Space Bar to display the information. Climographs • A climograph, or climate graph, combines a line graph and a bar graph. • It gives an overall picture of the climate–the long-term weather patterns–in a specific place. • Because climographs include several kinds of information, you need to read them carefully. (page 12) Click the mouse button or press the Space Bar to display the information. Climographs (cont.) • Note that the vertical bars on the climograph on the following slide represent average amounts of precipitation (rain, snow, or sleet) in each month of the year. (page 12) Climographs (cont.) (page 12) Climographs (cont.) • These bars are measured against the axis on the right side of the graph. • The line plotted above the bars represents changes in the average monthly temperature. • You measure this line against the axis on the left side of the graph. • The names of the months are shown in shortened form on the bottom axis of the graph. (page 12) Click the mouse button or press the Space Bar to display the information. Diagrams • Diagrams are drawings that show steps in a process, point out the parts of an object, or explain how something works. • You can use a diagram to assemble a stereo. • The diagram on the following slide shows how locks enable ships to move through a canal. (page 13) Click the mouse button or press the Space Bar to display the information. Diagrams (cont.) (page 13) Diagrams (cont.) • An elevation profile is a type of diagram that can be helpful when comparing the elevations of an area. • It shows an exaggerated profile, or side view, of the land as if it were sliced and you were viewing it from the side. • The elevation profile of Africa on the following slide clearly shows low areas and mountains. • The line of latitude at the bottom tells you where this profile was “sliced.” (page 13) Click the mouse button or press the Space Bar to display the information.
