Quick Answer: How Is Class 10 Soil Erosion Controlled?

How can soil erosion be controlled?

The 3 main principles to control erosion are to:use land according to its capability.protect the soil surface with some form of cover.control runoff before it develops into an erosive force.Dec 18, 2013.

How can we protect the soil?

Let’s take a look at 25+ ways to protect and conserve the soil.Forest Protection. The natural forest cover in many areas has been decreased due to commercial activity. … Buffer Strips. … No-Till Farming. … Fewer Concrete Surfaces. … Plant Windbreak Areas. … Terrace Planting. … Plant Trees to Secure Topsoil. … Crop Rotation.More items…

What is soil erosion mention any four steps to control erosion?

Two ways to prevent soil erosion are:Shelter belts: Trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind.Constructing dams: Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.

What is a good example of erosion?

Some of the most famous examples of erosion include the Grand Canyon, which was worn away over the course of tens of millions of years by the Colorado River with the help of winds whipping through the formed canyon; the Rocky Mountains in Colorado have also been the subject of intense geological study, with some …

What happens when erosion takes place?

Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. … When the water freezes it expands and the cracks are opened a little wider. Over time pieces of rock can split off a rock face and big boulders are broken into smaller rocks and gravel.

What steps can be taken to control soil erosion Class 10?

Following steps are taken to control the soil erosion in hilly areas: (i) Contour ploughing: this refers to ploughing along contour lines. (ii) Terrace farming: construction of steps along the hilly areas by cutting the rock layers to reduce the flow of rivers. (iii) Plugging of gullies to prevent gully erosion. 4.

How can erosion be prevented?

Crop Rotation: Rotating in high-residue crops — such as corn, hay, and small grain — can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water. Conservation Tillage: Conventional tillage produces a smooth surface that leaves soil vulnerable to erosion.

What are 3 methods of soil conservation?

Soil conservation methodsAfforestation.Checking Overgrazing.Constructing Dams.Changing Agricultural Practices.Crop Rotation.Strip Cropping.Use of Early Maturing Varieties.Contour Ploughing.More items…

What is soil erosion and soil conservation class 10?

The loss of soil cover due to natural agents like wind and running water is called soil erosion. … The roots of plants and trees keep the soil moist and hold the soil particles together. Humans destroy vegetation cover by deforestation, overgrazing, construction and mining activities.

Is erosion a slow or fast process?

Some changes are due to slow processes, such as erosion and weathering, and some changes are due to rapid processes, such as landslides, volcanic eruptions, Tsunamis and earthquakes.
