Answer 1

Answer:

Explanation:

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 (glaciers), snow, air (wind), plants, animals, and humans. In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic erosion and anthropogenic erosion such as tillage erosion.[1] Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an alarming rate causing a serious loss of topsoil. The loss of soil from farmland may be reflected in reduced crop production potential, lower surface water quality and damaged drainage networks. Soil erosion could also cause sinkholes.

Human activities have increased by 10–50 times the rate at which erosion is occurring globally. Excessive (or accelerated) erosion causes both "on-site" and "off-site" problems. On-site impacts include decreases in agricultural productivity and (on natural landscapes) ecological collapse, both because of loss of the nutrient-rich upper soil layers. In some cases, the eventual end result is desertification. Off-site effects include sedimentation of waterways and eutrophication of water bodies, as well as sediment-related damage to roads and houses. Water and wind erosion are the two primary causes of land degradation; combined, they are responsible for about 84% of the global extent of degraded land, making excessive erosion one of the most significant environmental problems worldwide.[2][3]

Intensive agriculture, deforestation, roads, anthropogenic climate change and urban sprawl are amongst the most significant human activities in regard to their effect on stimulating erosion.[4] However, there are many prevention and remediation practices that can curtail or limit erosion of vulnerable soils.

Answer 2

Soil erosion is the natural phenomena of a areas topsoil being stripped away, impacting land surfaces.

• Its effects include -

1. Destruction of ecosystems and deforestation, resulting in biodiversity drop.It leads to the degradation of land, thereby depleting the resources.
2. Overgrazing happens when animals like sheep, cows, or goats are in excess on the farm. By consuming vegetation and digging into wet soil or the animals do damage to the soil surface.

• Steps to lessen its impact are are -

1. Crop rotation -  Enables farmers to increase the quality of soil organic matter, soil structure and deep rooting. It is achieved by cultivating secondary crops that boost soil quality.
2. Crop Covering - It is a method to cover the soil and is effective to reduce soil erosion and also protects against heavy rainfall.
3. Mulching - It refers to the application of some organic material to soil to increase its richness.
