Maps are used to locate places and show distributions of features on Earth's surface. There are different types of map projections that show shapes and sizes of landmasses in different ways. Topographic maps model elevation changes using contour lines and indicate natural and human-made features. Geologic maps show the arrangement and types of rocks at the surface and below.
