The 5 Themes of Geography This approach was first used by Geographers to help study different areas on the earth’s surface. By using this logical approach, it helped Geographers stay focused. The five themes were written in 1984 by the Joint Committee on Geographic Education of the National Council for Geographic Education (NCGE) and the Association of American Geographers (AAG). They are outlined in greater detail in the NCGE/AAG publication Guidelines for Geographic Education, Elementary and Secondary Schools. (off the internet-national geographic.com) Notes on 5 themes review Unit 4 Geography Is the study of: -The earth -Its resources -How we use those resources -How we affect the environment -How the environment affects us. Types of Geography Physical-studies natural features (land, water, etc) Cultural- (Human) studies humans and how they impact the planet (language, culture, etc) Economic- studies how humans make a living Strategic-studies how humans use their environment Key Geographic Terms Resources- gifts from the earth, are limited Geographic terms continued Peninsula- body of land surrounded by water on three or more sides Key Terms continued Water bodies Ocean- the whole body of salt water that covers nearly three fourths of the surface of the earth. http://go.hrw.com/atlas/norm_htm/ocean s.htm Sea- large body of salt water that is partially or almost totally surrounded by land. (pp 165 Don’t know much about Geography) Gulfs- large deep inlets of the ocean or sea surrounded by land or an extensive inlet penetrating far into the land. http://www.weather.com/maps/geograph y/oceans/gulfofmexicosatellite_large.html Terms continued Bays- simply a large indentation into the land formed by the sea. smaller than Gulfs. Note: some gulfs and bays are larger than Seas. http://earthobservatory.nasa.gov/Newsroom/N ewImages/images.php3?img_id=17322 Continent- large landmass (7) pp 81 Don’t know…. Pangaea Globe- model of the earth Map- flat representation of the earth Key terms continued Landforms- structures/formation of land. Types of Maps Physical- Shows physical features http://www.worldatlas.com/aatlas/infopag e/physical.htm Political- Shows political features such as boundaries, cities, countries, etc http://www.mapsofworld.com/africapolitical-map.htm Road- Aids in transportation http://www.aaccessmaps.com/show/map/ oahu Key Map Terms Title Key / Legend Date Direction Scale http://www.mapsofworld.com/afric a-political-map.htm Review Latitude and Longitude Latitude and Longitude Continued Time Earth is 360 degrees/24 hrs in a day(24 time zones) For every 15 degrees = 1hr Going to the East you add an hour, going to the West you subtract an hour. http://www.worldtimezone.com/da tetime.html Definition Latitude- Lines that run East and West but measure North and South. Longitude- Lines that run North and South but measure East and West. - Example (22° N, 153° W) The Equator and Prime Meridian split the earth into Hemispheres (North, South, East and West) . Helps find location. Earth Quick Facts Earth is 4 ½ billion years old Circumference is 25,120 miles Diameter is 8000miles pole to pole is 27899 miles equator is 27926 miles Area is 196,800,000 sq miles Rotation takes 23 hrs 56 minutes and 4 seconds Speed on axis is 1000 mph Speed of revolution is 67,000 mph (elliptical) Takes 365 ¼ days to complete one year Earth is tilted at 23 ½ degrees and slightly wobbles Climate and Weather Climate: meteorological conditions of a region over a long period of time. (Koppen) (13 Climate regions divided into 4 categories) - High lands – Sub arctic, Tundra, Ice Cap, Highlands -Dry- Steppe, Desert -Mid Latitude- Mediterranean, Humid Subtropical, Humid Continental (W S and CS) and Marine West Coast Tropical- Tropical Rain forest, Savanna Climate and Weather Continued Weather: day to day atmospheric conditions of a region. There are four Effects on Climate and Weather 1. Earth/ Sun Relationship http://esminfo.prenhall.com/scie nce/geoanimations/animations/0 1_EarthSun_E2.html Effects on Weather and Climate Key things to know: -Solstices- two times during the year when the tilt of the earth is closest or farthest from the sun. (Winter is Dec 21st and Summer is June 21st for the northern hemisphere) Equinoxes- two times during the year when the earth is as perpendicular to the suns rays as it will ever be. During this time, there is equal amounts of sunlight and darkness in both hemispheres. (Fall occurs approximately Sept 22nd and Spring occurs approximately March 21st) Perihelion –when the earth is closest to the sun (146.24 million Kilometers or 91 million miles) Aphelion –when the earth is farthest away from the sun (151.36 million Kilometers or 95 million miles) Effects Continued 2 Location next to large bodies of water. Rule : Average temps don’t fluctuate more than 40 degrees Effects of Large Bodies of Water. Sources: National Climatic Data Center and Wayne Barnes, Weather Services Corp. From 70s to near 100 normal around Los Angeles Normal summer days in the Los Angeles area bring cool, Pacific breezes and ocean clouds that help hold high temperatures in the 70s near the coast. But as you go eastward from places such as Santa Monica, away from the ocean, temperatures become warmer and warmer. For much of the region, August temperatures are warmer than July's because the ocean continues warming up well into August. But, San Bernardino is far enough from the ocean that its normal temperatures follow the pattern of most inland places, July is warmer than August.
