Map Projections

*What’s the difference between a globe and a map?

*this becomes an issue when trying to represent a sphere shape onto a flat piece of paper

Map Projection Map projection: way of showing spherical earth on a flat piece of paper

*basically, EVERY world map you see is wrong in some way

*maybe this will help you understand: https://www.youtube.com/watch?v=av1cQr5b4KM

*Mercator Projection*What do you notice about this projection?

*What is good about it, and what is not so good?

Problems with Mercator Projection*land masses that are closer to the poles appear MUCH larger than they actually are (this is called distortion)
