What is soil erosion Class 9 short answer?
“Soil erosion is the natural process in which the topsoil of a field is carried away by physical sources such as wind and water.”.
What are 3 methods of soil conservation?

Why do we need to prevent soil erosion?
Topsoil, which lies closest to the surface of the land, contains essential nutrients for crops. It is this layer of soil that is endangered by wind and water erosion. Soil erosion decreases soil fertility, which can negatively affect crop yields. … Once soil erosion occurs, it is more likely to happen again.
What action can humans take to help prevent erosion?
There are many methods that could be used to help prevent or stop erosion on steep slopes, some of which are listed below.Plant Grass and Shrubs. Grass and shrubs are very effective at stopping soil erosion. … Use Erosion Control Blankets to Add Vegetation to Slopes. … Build Terraces. … Create Diversions to Help Drainage.Oct 17, 2016
How can we prevent soil erosion Class 9?
Preventive methods of soil erosion (i) Afforestation Planting more trees reduces soil erosion. (ii) Contour Ploughing Ploughing land in furrows across the natural slope of the land helps trap water and prevent the washing away of top soil along with it.
What are three ways to prevent soil erosion?
You can reduce soil erosion by:Maintaining a healthy, perennial plant cover.Mulching.Planting a cover crop – such as winter rye in vegetable gardens. … Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.More items…
How does class 7 prevent soil erosion?
Soil erosion can be prevented in the following ways: Soil erosion can be prevented by preventing large scale cutting down of forest trees. … Soil erosion can be prevented by afforestation (large scale growing of forest trees in place of cut down trees).More items…•Mar 20, 2019
What are the best plants that help prevent soil erosion?
Cover crops, such as vetch, rye and clover, are excellent plants for erosion control. These hardy easy to grow plants send out nets of roots that help hold topsoil in place while also reducing competitive weeds. When tilled back into the soil, they increase the nutrient density as they compost.
What is Soil Erosion give two methods of reducing it?
The four most common soil erosion prevention methods are vegetation, geotextiles, mulch, and retaining walls. Preventing soil erosion is critical in protecting your property and exposed soil, whether from wind, weather, running water, and even the after-affects of forest fire.
How do you fix erosion damage?
For heavy erosion in areas of concentrated flow, the most effective solutions are check dams or terraces.Replant Vegetation Suited to Site Conditions. Well-established vegetation can stabilize the soil in cases of light erosion. … Footpaths with Exposed Soil: Cover with Mulch or Gravel. … Terraces. … Build Check Dams.
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 is Soil Erosion very short answer?
Soil erosion is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing away of a field’s topsoil by the natural physical forces of water (Figure 1) and wind (Figure 2) or through forces associated with farming activities such as tillage.
How is Class 10 soil erosion controlled?
Ans. 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.

The most natural form of erosion in the examples is C, waves washing over rocks on the beach. … In B, this is the acid rain, and in D it is the erosion of soil that occurs due to the off-road vehicles.
What is erosion example?
Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock. One example is called frost action or frost shattering. Water gets into cracks and joints in bedrock.
What are 2 or 3 ways to prevent erosion and conserve soil?
Planting Vegetation as ground cover: Farmers plant trees and grass to cover and bind the soil. Plants prevent wind and water erosion by covering the soil and binding the soil with their roots. The best choice of plants to prevent soil erosion are herbs, wild flowers and small trees.
