Question 1

What are the four types of distortion that can occur with a map projection.

Answer 1

shape, distance, relative size, direction.

Ex: The shape of an area can be distorted, so that it appears more elongated or squat than in reality.
The distance between two points may become increased or decreased.
The relative size of different areas may be altered, so that one area may appear larger than another on a map but is in reality smaller.
The direction from one place to another can be distorted.

Question 2

What is the primary benefit of using a equal area projection?

Answer 2

the relative sizes of the landmasses on the map are the same as in reality. The projection minimizes distortion in the shapes of most landmasses, although areas toward theNorth and South poles—such as Greenland and Australia- become more distorted.
