The movement of ice in the form of glaciers has transformed our mountainous land surfaces with its tremendous power of erosion. U-shaped valleys, hanging valleys, cirques, horns, and aretes are features sculpted by ice. The eroded material is later deposited as large glacial erratics, in moraines, stratified drift, outwash plains, and drumlins.
The whole process of landform formation is known as erosion. Erosion is the wearing away of the earth’s surface by the action of natural forces, for example, water, wind and glacial ice. The loose and dissolved materials move from one location to another. Erosion should not be confused with weathering.
Types of Water Erosion. While there are several types of water erosion, they can generally be grouped into four major types: Inter-rill erosion; Rill erosion; Gully erosion; Bank erosion; Let’s have a detailed look at them. 1. Inter-rill Erosion. Inter-rill erosion describes the movement of topsoil by rainfall and its resultant surface flow.
Fluvial erosion is the process by which a river wears away the land. The ability of a river to erode depends on its velocity. Two types of erosion happen at different stages along a river. Vertical (downwards) erosion often occurs in the upper stages of a river, whereas lateral (sidewards) erosion typical occurs in the middle and lower stages ...
The two main types of erosion are: Abrasion close glacial abrasion A type of glacial erosion that occurs when rock fragments that are frozen into the bottom of a glacier scrape and erode the ...
Aug 17, 2021 · Weathering is a process that turns bedrock into smaller particles, called sediment or soil. Mechanical weathering includes pressure expansion, frost wedging, root wedging, and salt expansion. Chemical weathering includes carbonic acid and hydrolysis, dissolution, and oxidation. Erosion is a mechanical process, usually driven by water, wind ...
Apr 23, 2024 · Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion. Splash erosion describes the impact of a falling raindrop, which can scatter tiny soil particles as far as 0.6 meters (two feet). Sheet erosion describes erosion caused by runoff.
