Question

what is soil erosion?​

Answer 1

Answer:

* It is a process in which the top fertile layer of soil is lost.

*Due to soil erosion, the soil becomes less fertile.

* The top layer of soil is very light which is easily carried away by wind and water.

soil erosion

• Soil erosion is a gradual process of movement and transport of the upper layer of soil (topsoil) by different agents – particularly water, wind, and mass movement – causing its deterioration in the long term.

• In other words, soil erosion is the removal of the most fertile top layer of soil through water, wind and tillage.

What Is Soil Erosion? A Soil Erosion Scientific Definition

According to a Pereira and Muñoz-Rojas (2017) synthesis, soil erosion is one of the major causes, evidence of, and key variables used to assess and understand land degradation. Soil erosion is a consequence of unsustainable land use and other disturbances, such as fire, mining, or intensive agricultural uses. The loss of soil may have serious impacts on the quantity and quality of soil ecosystem services, with serious economic, social, and political

Different Soil Erosion Causes

• Soil erosion is a complex process that depends on soil properties, ground slope, vegetation, and rainfall amount and intensity. According to Montgomery, modifications in land use are one of the most impactful ways of accelerating soil erosion. These changes then have a cascade effect as the loss of fertile topsoil cover sends millions of tons of sediments into lakes and reservoirs, changing ecosystems and impacting agricultural production and water quality. This has been the case with the Bo River in Vietnam.

• According to Al-Kaisi from Iowa State University, there are 5 main types of natural soil erosion:

• 1) Sheet erosion by water;
• 2) Wind erosion;
• 3) Rill erosion – happens with heavy rains and usually creates smalls rills over hillsides;
• 4) Gully erosion – when water runoff removes soil along drainage lines
• 5) Ephemeral erosion that occurs in natural depressions.
