Detailed explanation-1: -Abrasion is a process of erosion which occurs when material being transported wears away at a surface over time. It is the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials.

Detailed explanation-2: -Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.

Detailed explanation-3: -Three agents of physical weathering that can cause abrasion are moving water, wind and gravity. Also Rocks suspended in the ice of a glacier can cause abrasion of other rock on earths surface. And moving water rocks can become rounded and smooth.

Detailed explanation-4: -In geography, abrasion refers to a form of erosion in which pebbles and other sediment are ground along a solid surface. The friction from this causes the surface to slowly erode over time. There are different types of abrasion-river, coastal, wind and glacial.

Detailed explanation-5: -The four main types of river erosion are abrasion, attrition, hydraulic action and solution. Abrasion is the process of sediments wearing down the bedrock and the banks. Attrition is the collision between sediment particles that break into smaller and more rounded pebbles.
