*What is the most common purpose that you use maps for?
![Page 2: *What is the most common purpose that you use Warm ups 8.24 · Map Projection Map projection: way of showing spherical earth on a flat piece of paper *basically, EVERY world map you](https://reader035.vdocuments.mx/reader035/viewer/2022063006/5fb77135e51acc31e31a6ba4/html5/thumbnails/2.jpg)
Lesson Objective:*Identify various parts of a map and explain their purpose
*identify different types of maps and their purposes

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?
![Page 6: *What is the most common purpose that you use Warm ups 8.24 · Map Projection Map projection: way of showing spherical earth on a flat piece of paper *basically, EVERY world map you](https://reader035.vdocuments.mx/reader035/viewer/2022063006/5fb77135e51acc31e31a6ba4/html5/thumbnails/6.jpg)
Problems with Mercator Projection*land masses that are closer to the poles appear MUCH larger than they actually are (this is called distortion)
