Question

Why is reading the map key important when looking at a special-purpose map

Answer 1

limestone, hydropower, geothermal energy, and coal

Answer 2

When you see a special purpose map, you have no idea what it is representing as it could represent everything from the amount of bikes in an area to geographical landscapes. When you look at the key, you know what each color/pattern stands for and can easily interpret the map. Hope i helped!
