Lithosphere and erosion
Download as PPTX, PDF0 likes1,128 views
The document discusses the lithosphere and erosion. It defines the lithosphere and lists some internal geological processes like earthquakes and volcanic eruptions. It also discusses external geological processes like different types of erosion caused by water, wind, human activity, glaciers, and more. Specifically, it outlines some examples of anthropic erosion caused by inadequate agricultural practices, removing vegetation, and forest fires. The consequences of anthropic erosion include desertification, loss of nutrients, floods, and more.
