When the wind blows away smaller, finer particles, the desert surface is rockier, causing the ground to subside (known as deflation). The groundwater slowly dissolves and carries away the solid rock which enlarges cracks and forms caves. Not only does wind erosion damage the land by drying out the soil and reducing the nutrients of the land, but it can also cause air pollution. 10(ah) Eolian Processes and Landforms - Physical Geography Further, the degree of wind abrasion is determined by the quantity and size of particles lifted above the surface. What landforms are formed by weathering and erosion? These effects are called deflation or abrasion. Not only does wind erosion damage the land by drying out the soil and reducing the nutrients of the land, but it can also cause air pollution.

The size of these eroded depressions varies from small to very large depressions. Erosion by water starts with rain. Shores may also be lined with barrier islands, small pieces of land that act as a defense against storms. The material in suspension is thus deposited. When airborne particles cause landmass to wear away or erode, on the other hand, this is an example of abrasion. Weathering is the division and separation of particles by both mechanical and chemical forces. Although they are too big to be suspended, these particles are light enough to be lifted off the surface. This cookie is set by GDPR Cookie Consent plugin. Loess deposits are found in Austalia also.

Among the most interesting and most beautiful landforms of weathering are those which develop in regions of limestone bedrock. Dark sand sinks to the bottom of the lake and then when the ice melts a layer of light sand is deposited. They create a vertical wall of exposed rock layers. Surfaces that have been worn away at by grain are called ventifacts. It is a mound, a hill, or a ridge of sand with a crest or a definite summit. Wind erosion processes consist of abrasion, the scouring of exposed surfaces by the sand-blasting action of wind-borne material; and deflation, the removal of sand-sized and smaller particles by the wind. Landforms Part-II - Drishti IAS When the velocity of the wind decreases, it starts dropping its load. Gravity, water, wind, and heat can all contribute to erosion.
