5. Mercator Projection Most common type of projection

Mercator Projection

6. Robinson Projection NOT equal area Deformation gets worse away from 0
Meridians curve closer to the poles
DOES fit the entire earth on one map

7. Peters Projection Equal area projection
Often used in educational circles
does not distort area.

8. Interrupted Projections
Interrupted projections can be tricky.
Maps are not "whole"
It becomes difficult to navigate the "gaps"

9. Specialized Maps 1. Topography 2. Vegitation 3. Political
