USA HISTORY

Detailed explanation-1: -erosion, removal of surface material from Earth’s crust, primarily soil and rock debris, and the transportation of the eroded materials by natural agencies (such as water or wind) from the point of removal.

Detailed explanation-2: -What Causes Erosion? Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.

Detailed explanation-3: -Rain works to erode the land on which it falls through rain-splash erosion, which is rain splashing down on the land and dislodging weathered material such as pebbles or soil. Heavy rainfall or large amounts of melting snow or ice can also carry away the sediment into streams and rivers.

Detailed explanation-4: -Physical Erosion Clastic sediments are composed of fragments of older rocks that have been transported from their place of origin. Landslides and other forms of mass wasting are associated with physical weathering. These processes cause rocks to dislodge from hillsides and crumble as they tumble down a slope.
