How does the erosion caused?
Answers
Answer:
The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth. ... Rainfall - Rainfall can cause erosion both when the rain hits the surface of the Earth, called splash erosion, and when raindrops accumulate and flow like small streams.
Answer:
Deep in the Mau forest of Kenya, Wilson Maritim, a local farmer, was on the verge of giving up his livelihood.For generations, the agricultural craft that had been honed by his family was literally slipping away, eroding in front of his very eyes. The Mara – the river that watered his farm, had been slowly degrading and eroding the soil in his area for decades.The devastation caused by this erosion was swift and severe.Today, however, Maritim and his fellow farmers in the Mara region are seeing stark improvements through creative but natural-based solutions; their wilting crops of beans and maize have been revived through soil and water conservation programs run by the World Wildlife Fund.But this is a problem that faces more than one region. It faces the world.In this article, we’re going to look at what soil erosion is, what causes it, and how it affects everyone on the planet.
Explanation:
CAUSE #1: HEAVY RAINFALLS AND RESULTING FLOODS
Heavy rainfalls can bring several types of soil erosion, including "rill" erosion, "gully" erosion, "sheet" erosion, and "splash" erosion. When raindrops hit the surface of the soil, they break down and disperse these particles, washing them away in runoff. Too much of this and there will be flooding, including flash floods and extreme local erosion of the bedrock.
Excess surface water and not enough land to support rainwater causes these loosened particles wash away.
CAUSE #2: HIGH WINDS
On the opposite end of the spectrum are high winds. Especially in drier climates or seasons, this can be an issue. Areas that are naturally arid or semi-arid are particularly vulnerable.
Like water, high winds can whip up already loosened soil particles and further devastate the topsoil.
It then carries these particles away, depositing them in waterways and other areas, making its mark on soil beds with its slow but steady force.
