• 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.

4. Constructing Dams:
5. Changing Agricultural Practices:
6. (i) Crop Rotation:
7. (ii) Strip Cropping:

Which of the following method are practically used to stop or control of soil erosion?

Answer: Afforestation- planting trees so that it could bind the soil in it. 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.

Which of the following is a method used to prevent soil depletion 2 points?

The best method used to prevent soil depletion would be contour farming. In contour farming, the land is tiled in consistent elevation. Contour farming is efficient in reducing soil depletion because it can conserve rain water and reduce the erosion of soil.

How can soil erosion be reduced where trees are logged?

Avoid logging steep hillsides. Cut only a few trees in any given place. Once the soil is in place, plant trees and other plants to protect the bare soil. Use barriers to prevent runoff and soil erosion at construction sites.

What are the method of preventing soil erosion?

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 3 methods of soil conservation?

Soil conservation methods

• Afforestation.
• Checking Overgrazing.
• Constructing Dams.
• Changing Agricultural Practices.
• Crop Rotation.
• Strip Cropping.
• Use of Early Maturing Varieties.
• Contour Ploughing.

What are the 4 methods of soil conservation?

Soil conservation practices are tools the farmer can use to prevent soil degradation and build organic matter. These practices include: crop rotation, reduced tillage, mulching, cover cropping and cross-slope farming. farmers to increase soil organic matter content, soil structure and rooting depth.

How is Class 10 soil erosion controlled?

The soil erosion can be prevented by the following ways:

1. Afforestation. Planting new trees and plants is afforestation.
2. Crop Rotation.
3. Terrace Farming.
4. Building Dams.
5. Shelterbelts.
6. Embankments.
7. Van Mahotsav.

What is soil erosion Class 6?

“Soil erosion is the natural process in which the topsoil of a field is carried away by physical sources such as wind and water.”

How can we prevent soil erosion in hilly areas?

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.

What are the major effects of soil erosion?

The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

What are the 5 effects of soil erosion?

Some of the greatest effects of soil erosion include:

1. Loss of Topsoil. Obviously, this is the biggest effect of soil erosion.
2. Soil Compaction.
3. Reduced Organic and Fertile Matter.
4. Poor Drainage.
5. Issues With Plant Reproduction.
6. Soil Acidity Levels.
7. Long Term Erosion.
8. Water Pollution.

What is the cause and effect of soil erosion?

Soil erosion decreases soil fertility, which can negatively affect crop yields. It also sends soil-laden water downstream, which can create heavy layers of sediment that prevent streams and rivers from flowing smoothly and can eventually lead to flooding. Once soil erosion occurs, it is more likely to happen again.

What are the five causes of erosion?

5 Common Causes of Soil Erosion

• Water. Water is very effective at doing work.
• Wind. Although wind usually erodes soil more slowly than water, Florida does have an active hurricane season from June to November.
• Gravity. When thinking about soil erosion, gravity often worked in conjunction with water and wind.
• Construction.
• Recreational Activities.

What are 3 things that can cause erosion?

The three main forces that cause erosion are water, wind, and ice. Water is the main cause of erosion on Earth. Although water may not seem powerful at first, it is one of the most powerful forces on the planet.

What are 4 main causes of erosion?

Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment. Rainfall produces four types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.

What are the 4 types of erosion?

The four main types of river erosion are abrasion, attrition, hydraulic action and solution. Abrasion is the process of sediments wearing down the bedrock and the banks.

What type of erosion causes waterfalls?

Soft rock erodes more quickly than hard rock. In places where the river’s course takes it over both hard and soft rock surfaces, the different rates of erosion may gradually lead to the formation of waterfalls and rapids. Waterfalls are created when the riverbed changes suddenly from hard rock to soft rock.

What are the main processes of erosion?

There are five main processes which cause coastal erosion. These are corrasion, abrasion, hydraulic action, attrition and corrosion/solution. Corrasion is when waves pick up beach material (e.g. pebbles) and hurl them at the base of a cliff.

Is Solution a type of erosion?

Erosion is the process that wears away the river bed and banks. Erosion also breaks up the rocks that are carried by the river. There are four types of erosion: Solution – When the water dissolves certain types of rocks, eg limestone.

What are the 3 types of weathering?

It does not involve the removal of rock material. There are three types of weathering, physical, chemical and biological.

What are 4 types of transportation?

Transport

• Solution – minerals are dissolved in the water and carried along in solution.
• Suspension – fine light material is carried along in the water.
• Saltation – small pebbles and stones are bounced along the river bed.
• Traction – large boulders and rocks are rolled along the river bed.

What are the four main types of weathering?

There are four main types of weathering. These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering. Most rocks are very hard. However, a very small amount of water can cause them to break.

What are 5 examples of weathering?

These examples illustrate physical weathering:

• Swiftly moving water. Rapidly moving water can lift, for short periods of time, rocks from the stream bottom.
• Ice wedging. Ice wedging causes many rocks to break.
• Plant roots. Plant roots can grow in cracks.

What are 4 factors that affect weathering?

Factors affecting weathering

• rock strength/hardness.
• mineral and chemical composition.
• colour.
• rock texture.
• rock structure.

What are the factors that affect physical weathering?

There are two factors that play in weathering, viz. Temperature and Precipitation. Warm climates affect by chemical weathering while cold climates affect by physical weathering (particularly by frost action). In either case the weathering is more pronounced with more moisture content.

What are the three main causes of weathering?

Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. There are two types of weathering: mechanical and chemical.

What is the main cause of chemical weathering?

Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.
