Absolute location- its exact position on the globe.
Relative location- locating a place by thinking of places in relation.
Latitude- imaginary parallels that circle the earth horizontally 0 to 90 Longitude- Imaginary meridians that circle the globe vertically going from 0 to 180 Grid System- lines of latitude and longitude cross one another making a grid.
Interdependent- relying on each other for goods, services, and ideas.
Culture- way of life.
Scale- certain measurement on a map represents a certain measurement on the earth's surface.

Map projection- way of representing the rounded earth on a flat surface.
Hemisphere- lines that cut the world on half.
Compass rose- direction marker.
Key- explains the symbols used on a map.
Mercator projection- shapes are fairly accurate but size and distance aren't. From the idea of wrapping a piece of paper in a cone shape and placing it on the globe.
Azimuthal projection- polar projection. Size and shape are distorted but distance and direction are accurate.
Conic projection- idea of placing a cone over a part of the globe. Accurate for small areas.
Diagrams- drawing showing how something or what something is done.
Charts and tables- show facts arranged in columns and rows.
Graphs-bar graph- shows comparisons. Line graph- shows changes in two variables. Circle graph- percentages to show how the parts of the whole compare.
Pictographs- special graphs using pictures.
Atmosphere- the air that surrounds the earth.
Earth measurements- earth is 93 million miles from the sun.
Hydrosphere- the water that makes up some of the earth biosphere- part of the earth where life is found/
