Through erosion, a river creates valleys, waterfalls, flood plains, meanders and oxbow lakes. Both processes happen over a long period of time, sometimes millions of years. The landforms which are created by erosional and depositional activities of wind are called Aeolian Landforms. 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. Want to know more about this Super Coaching ?

Pediplains When the high relief structures in deserts are reduced to low featureless plains by the activities of wind, they are called as Pediplains. For example, it can cause: While wind erosion will happen, there are a few things you can do to help keep it at bay. Creep is a gradual movement of soil downhill. Moving water is the major agent of erosion that has shaped Earth's land surface. Demoiselles are formed due to differential erosion of hard and soft rocks. Erosion by waves can create unique landforms ( Figure below). A dust storm's smaller particles can travel higher. When the wind dumps sand, it builds up on top of itself until a small mound forms. Theyre found in various biomes, and despite how sedentary some of them look, they are always changing.

Some of the landforms created by fluvial erosion include river valleys, oxbow lakes, waterfalls, sinkholes, and caves. Erosional Landforms formed by Wind. Winds are also capable of degrading the land, but their erosion and transportation ability is inferior to that of the water. The landforms formed due to processes of Wind are called Aeolian Landforms. rocks are formed in the desert regions by means of wind erosion, Wind is an important agent of transportation Wind loaded with sand in desert areas has an eroding effect on softer rocks over time.
