Detailed explanation-1: -Example of erosion: Wind carries small pieces of rock away from the side of a mountain. Chemical Weathering: – Decomposition of rock and soil due to chemical reactions.
Detailed explanation-2: -Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.
Detailed explanation-3: -1) Sheet erosion by water; 2) Wind erosion; 3) Rill erosion – happens with heavy rains and usually creates smalls rills over hillsides; 4) Gully erosion – when water runoff removes soil along drainage lines.
Detailed explanation-4: -Water. Water is the most common cause of soil erosion. Wind. Wind can also make soil erode by displacing it. Ice. We don’t get much ice here in Lawrenceville, GA, but for those that do, the concept is the same as water. Gravity. Gravity is a primary culprit behind the three other causes. 10-Dec-2020
