Define soil erosion? How it is caused? How it can be avoided?
Answers
Answer:
Soil Erosion is a process by which soil gets eroded from place to place. The agents of soil erosion are water and wind.
Explanation:
In simple words, soil erosion is a process where soil gets eroded by air
and water. This causes problems to houses, places etc.
To avoid this, we must grow more plants and trees because their roots will hold the soil from eroding.

Q :-
Define soil erosion? How it is caused? How it can be avoided?
A :-
Introduction :-
Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water and wind or through forces associated with farming activities such as tillage.
social erosion :-
The removal of fertile top soil land by wind or water is called soil erosion. Soil erosion occurs easily in those areas of land which are not covered by vegetation (trees and other plants) or have very little vegetation. The soil does not become loose easily and the flowing rainwater is not able to carry away top-soil.
Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, animals, and humans.
causes :-
Running water is the leading cause of soil erosion, because water is abundant and has a lot of power. Wind is also a leading cause of soil erosion because wind can pick up soil and blow it far away. Activities that remove vegetation, disturb the ground, or allow the ground to dry are activities that increase erosion.
Due to human activities like deforestation, overgrazing, construction and mining, etc. Natural forces like wind, glacier and water leads to soil erosion. The running water cuts through clayey soils and makes deep channels as 'gullies'. ... Sometimes, water flows as a sheet over large areas down a slope.
It is the natural process of wearing away of the topsoil, but human activities have accelerated the process. It is usually caused due to the removal of vegetation, or any activity that renders the ground dry. Farming, grazing, mining, construction and recreational activities are some of the causes of soil erosion.
how to avoided it?
Soil erosion affects soil health and productivity by removing the highly fertile topsoil and exposing the remaining soil. It decreases agricultural productivity, degrades ecosystem functions and amplifies hydrogeological risk, such as landslides or floods.
Soil degradation reduces agricultural yields and threatens farmers' livelihoods. Soil that has been leached of its nutrients cannot support crops, or plants that prevent desertification. Healthy soil is essential to ensure a steady supply of food and biodiversity.
