GEOLOGY

Detailed explanation-1: -Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment.

Detailed explanation-2: -But the most powerful erosive force on earth is not wind but water, which causes erosion in its solid form-ice-and as a liquid. Water in its liquid form causes erosion in many ways. Streams-from tiny creeks to huge rivers-carry tons of eroded earth every year.

Detailed explanation-3: -Gravity is probably the fastest agent of erosion because it leads to rapid landslides and mudflows. Water is the second fastest agent of erosion because it breaks down and transports sediments fairly quickly.

Detailed explanation-4: -Water erosion. This includes the splashing of soil particles by raindrop impact; sheet erosion whereby a layer of topsoil is removed by flowing water; and gully erosion where a channel is formed. Gullies are often perceived as the most serious form of water erosion because they are obvious features in the landscape.

Detailed explanation-5: -Wind cannot carry as large particles as flowing water, but easily pick ups dry particles of soil, sand and dust and carries them away. Wind generally causes erosion by deflation and/or abrasion.
