# Chapter 1 World Geography

Geography
the study of the distribution and interaction of physical and human features on the earth
Absolute Location
the exact place on earth where a geographic feature is found
Relative Location
describes a place in comparison to other places around it
Hemisphere
this is what each half of the globe is called
Equator
the imaginary line that divides the north and south halves
Prime Meridian
the imaginary line dividing the earth east and west
Latitude
imaginary lines that geographers and other people use to locate places north and south
Longitude
imaginary lines that go around the world over the poles. These lines mark positions in the east and west hemispheres.
Globe
a 3D representation of the earth
map
a 2D representation of the earth
cartographer
a map maker
Map Projection
a way of making the earths surface that reduces distortion caused by converting 3 dimensions into 2 dimensions
topographic map
a general reference map; a representation of natural and man-made features on the earth.
Landsat
a series of satellites that orbit more than 100 miles above Earth
Geographic Information System (GIS)
technology that uses digital map information to create a data bank; different data layers can be combined to produce specialized maps. GIS allows geographers to analyze different aspects of a specific place to solve problems.
Which of our terms indicate imaginary parallel lines that circle the earth?
Latitude, longitude, and equator
Which of the terms marks the beginning of longitude?
The prime meridian
Which of the above terms has 180 degrees in each hemispheres?
Longitude
How may hemispheres be divided?
By the equator and the prime meridian
What imaginary line separates the Northern Hemisphere from the Southern Hemispheres?
equator
Which term is also known as a meridian line?
longitude lines
Would a cartographer work on a map or a globe
both
Why are map projections needed?
Map projection shows the earth with much less distortion
Which of the terms are associated with the geographic grid?
latitude, longitude, prime meridian, and equator
Which term characterizes the study of the use of land space?
Geography
How is absolute location different from relative location?
Absolute location is the exact place on earth and relative location describes a place in comparison to other places around it.
What are some examples of information that would be included in a place description?
Physical features like rivers, mountains, etc. It also could include cultural aspects, climate, source of income, characteristic of a place, etc.
How is a place different from a region?
A place is one particular area or spot, where a region refers to a larger area of land or real estate.
Why do geographers study movement?
Studying this helps explain how people, goods, and ideas get from one place to another. It helps geographers understand the relationship among places.
What is the purpose of a map?
The purpose lies chiefly in navigation and in helping cultures determine new trade routes
How do satellites aid in mapmaking?
Satellites provide accurate data for a map
Why is GIS a valuable tool for examining the geography of a place?
It provides lots of information for one place
How is the use of a small scaled maps different from the use of a large scale map
Small scale maps show a large area without much detail. Large scale maps show a small area with much more detail
In what ways may relief be shown on a map?
