Overgrazing, which is when farmers allow livestock to graze to the point where they damage the vegetation, and deforestation, which is the process of removing trees and transforming a forest into cleared land, are also ways that humans cause desertification by removing vegetation.
Physical maps show different geographical features, bodies of water, and land forms.
