Question

what is soil erosion​

Answer 1

Answer:

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

Answer 2

Answer:

$\sf \: \bold \blue{What \: is \: Soil \: Erosion?}$

Soil Erosion is one form of soil degradation. It occurs in almost all types of lands. Flowing water, rainwater, and the wind are the prime agents which cause a significant amount of soil loss each year. Too much of soil erosion causes serious loss of topsoil and also reduces crop production potential, lower surface water quality, and damaged drainage networks.

$\red{\bold {Types \: of \: Soil \: Erosion}}$

One of the most important things that we can do to ensure the health of our crops and nearby ecosystems is to reduce soil erosion. The different soil erosion types are explained below.

$\pink{ \bold{Rain \: Drop \: or \: Splash \: Erosion}}$

The erosion due to the impact of falling raindrops on soil surface leading to the destruction of the crumb structure is known as the raindrop or splash erosion.

$\pink{\bold{Sheet \: Erosion}}$

It is the uniform removal of soil in thin layers from the land surface caused by the wind. Land areas with loose, shallow topsoil overlie compact soil are most prone to sheet erosion

$\pink{\bold {Rill \: Erosion}}$

Rill erosion is a form of water erosion in which the erosion takes places through numerous narrow and more or not so straight channels called streamlets, or head cuts. Rill is the most common form of erosion, which you can also observe during heavy rain.

$\pink{ \bold {Gully \: Erosion}}$

Gully erosion occurs due to the runoff of surface water causing the removal of soil with drainage lines. Gullies when started once, will move by headward erosion or even by slumping of side walls unless and un-till proper steps will be taken in order to stabilize the disturbance.

$\pink{\bold{Stream \: Bank \: Erosion}}$

Bank erosion is nothing but washing up away from banks of a stream or a river. It is different from the erosion of the bed of a watercourse, that is referred to as scouring. This type of erosion is also termed as Stream Bank Erosion.

$\red{\bold { Causes \: of \: Soil \: Erosion}} \:$

Running water is one of the main cause of soil erosion. Some soil erosion causes are mentioned below.

$\green{\bold{Due \: to \: Soil \: Texture}}$

If the texture is loose that is the soil contains more of small grains and of open structure erodes faster.

$\green{ \bold{Slope}}$

Soil present in a steeper slope more than the soil present at a plane level of the ground.

$\green{ \bold{Intensity \: or \: Amount \: of \: Rainfall}}$

More intense rain, more erosion. This can be a bit slow if there are more trees present in the land as the roots of the plants hold soil in a firm manner.

$\green{ \bold{Human \: Activities}}$

Agricultural practices, deforestation, roads and urbanization and global warming are a few major causes of soil erosion.

$\green{ \bold{Deforestation}}$

$\red{\bold { Soil \: Erosion \: Prevention}}$

Soil erosion is a serious environmental issue. Steps should be taken to curb this problem. Following are some of the methods of soil erosion prevention:

• Plant trees on barren lands to limit erosion of soil.

• Add mulch and rocks to prevent the plants and grass underneath to prevent soil erosion.

• Mulch matting can be used to reduce erosion on the slopes.

• Put a series of fibre logs to prevent any water or soil from washing away.

• A wall at the base of the slope can help in preventing the soil from eroding.

• Every household should have a proper drainage system so that water flows down into proper water collecting systems.
