THE 5 THEMES OF GEOGRAPHY
Defining Geography
What is Geography?
Geography is the study of the earth
and the way people live on it and use
it.
Geography:
Defining the Discipline
• Geographia (Greek origins)
– Geo (earth) + graphein (to describe or write)
– To write or describe the surface of the earth
• The study of the spatial arrangement and
association among elements on and/or in
contact with the earth’s surface
• Explaining the “big picture”
Geography:
Defining the Discipline
• Three defining questions…
– What is located where?
– Why are things located where they are?
– What is the significance?
The Geographic Perspective
• Understanding the ways in which humankind
perceives and interacts with the Earth’s
surface, its resources, and its people
• Geography lies at the intersection of both
social and physical sciences
• Explain the processes that give rise to spatial
distributions---it’s not all about maps!
• Geographic landscapes are social creations
The Geographer’s Perspective
• From Greek term
geographia
– “To describe the earth”
– Look at use of space
• Methods
– Maps
– Atlases, books,
electronic media
– Imagery (photos, etc)
– Five themes
Spatial variation: predominant religion
Why spatial variation exists: earthquakes
Changes over time: deforestation

street and turn left for 1
block.
Absolute Location

Home on the Range
Oh, give me a home where the buffalo roam
Where the deer and the antelope play
Where seldom is heard a discouraging word
And the skies are not cloudy all day
Home, home on the range
Where the deer and the antelope play
Where seldom is heard a discouraging word
And the skies are not cloudy all day
How often at night when the heavens are
bright
With the light from the glittering stars
Have I stood there amazed and asked as I
gazed
If their glory exceeds that of ours
Home, home on the range
Where the deer and the antelope play
Where seldom is heard a discouraging word
And the skies are not cloudy all day
Where the air is so pure, the zephyrs so free
The breezes so balmy and light
That I would not exchange my home on the range
For all of the cities so bright
Home, home on the range
Where the deer and the antelope play
Where seldom is heard a discouraging word
And the skies are not cloudy all day
Oh, I love those wild flow'rs in this dear land of
ours
The curlew, I love to hear scream
And I love the white rocks and the antelope flocks
That graze on the mountaintops green
Home, home on the range
Where the deer and the antelope play
Where seldom is heard a discouraging word
And the skies are not cloudy all day

Key Geography Terms and Skills
The Geographer’s Tools
• Globes
– Three dimensions
– Accurate not portable
• Maps & charts
– Two dimensional
– Drawn to any scale
– Different projections
• Scale models
• Types of maps
– General reference, thematic,
navigational
• Five Themes
Key Terms & Places
• Globe – A three-dimensional representation of
the earth.
• Map – Two-dimensional graphic
representations of selected parts of the
earth’s surface.
• Cartographer – A person who makes maps or
charts.
Understanding the Globe
• Earth is a huge sphere, like a ball. Most maps
show the earth’s surface as flat. A globe is a sphere.
Because of this, it provides an accurate map of our
planet.
• Compass: An instrument for finding directions.
• Cardinal Points: the four main
points on a compass – north, east,
south, and west.
• Intermediate Points: points in
between cardinal points –
northeast, northwest, northwest,
southeast, and southwest.
Understanding the Globe
• Equator: An imaginary line circles Earth halfway between
the north and south pole and divides the Earth into two half
spheres, called hemispheres.
•Prime Meridian: Another imaginary line that cuts the
Earth in half from the North Pole to the South Pole.
Western
Eastern
Equator
Prime
Meridian
Understanding the Globe
• Over 70% of our planet is covered in water, mainly
oceans.
• Oceans are the largest bodies of water. There four
oceans. From largest to smallest, they are
– Pacific Ocean
– Atlantic Ocean
– Indian Ocean
– Arctic Ocean
Understanding the Globe
• Oceans surround large landmasses called continents
• The seven continents on Earth, from largest to
smallest, are Asia, Africa, North America, South
America, Antarctica, Europe, and Australia.
Types of Maps
• General reference
– AKA topographic
– Natural & man-made
features of earth
• Thematic
– Specific information
– Climate, population
• Navigational
– AKA charts
– Pilots’ & sailors’ use
Nautical Chart (detail)
Geographic Skills
• Finding a location
– Use of maps, charts,
GPS, compass, etc
• Reading a map
– Title, compass rose,
labels, legend (key),
parallels of latitude,
meridians of longitude,
scale, symbols, colors
The Parts of a Map
Compass Rose
• A compass rose is a model of a compass. It tells the
cardinal directions, which are north, south, east, and
west.
Scale
• The scale on a map tells you the relative distance on
the map to the real world. For example, a map’s scale
may tell you that one inch on the map equals one
mile in the real world.

Key
• The key, or legend, on a map explains what the
symbols on a map represent, such as triangles
representing trees.
Grids
• Some maps use a grid of parallels and meridians.
On a map of a small area, letters and numbers are
often used to help you find your location.
OwlTeacher.com
Understanding Latitude and Longitude
• latitude and longitude – types of measurement that
can pinpoint any spot on Earth
• Latitude lines – run west to east (p.14)
– Always have the same distance in between them.
– Are measured starting at the equator.
– Equator – 0 ° latitude
– North Pole - 90° latitude
– South Pole - 90° latitude
Understanding Latitude and Longitude
• Longitude lines – lines that run from the North Pole to
the South Pole.
– Not always the same distance apart
– Starting place for measuring them is the Prime
Meridian
– Prime Meridian is at 0 degrees longitude
Understanding Latitude and
Longitude
• To note a place on Earth, first name its
latitude, then its longitude.
• For example, one location on Earth’s surface is
at 30 degrees N, 90 degrees W. Can you find
this location on the map on page 15?

Getting It All On the Map
The World: Mercator Projection
OwlTeacher.com
• In 1569, a geographer
named Gerardus Mercator
created a flat map to help
sailors navigate long
journeys across the globe.
• The Mercator projection, or
method of putting a map of
the Earth onto a flat piece of
paper, is used by nearly all
deep-sea navigators.
• The Mercator projection is a
conformal map, meaning
that it shows correct
shapes, but not true
distances or sizes.
• There are many types of
other projections of the
globe.
The World: Three Projections
Interrupted Projection
There are many ways to show a globe
on a flat map. The interrupted
projection map, on the left, shows
real sizes and shapes of continents.
The equal area map , below left,
shows size accurately. The Peters
projection, below, shows land and
oceans areas and correct directions
accurately
