Which of the following is NOT a natural factor contributing to soil erosion?

  1. Wind

  2. Water

  3. Human activities

  4. Gravity


Correct Option: C
Explanation:

Human activities such as deforestation, overgrazing, and poor farming practices are the primary causes of soil erosion.

The process of soil erosion by wind is known as:

  1. Deflation

  2. Abrasion

  3. Corrosion

  4. Deposition


Correct Option: A
Explanation:

Deflation is the process by which wind removes soil particles from the surface of the earth.

Which of the following is NOT a human activity that can accelerate soil erosion?

  1. Deforestation

  2. Overgrazing

  3. Contour plowing

  4. Terracing


Correct Option: C
Explanation:

Contour plowing is a farming practice that helps reduce soil erosion by creating ridges and furrows that slow down the flow of water.

The rate of soil erosion is influenced by the:

  1. Soil texture

  2. Soil structure

  3. Slope of the land

  4. All of the above


Correct Option: D
Explanation:

The rate of soil erosion is influenced by a combination of factors including soil texture, soil structure, and the slope of the land.

Which of the following soil types is most susceptible to wind erosion?

  1. Sandy soil

  2. Clayey soil

  3. Loamy soil

  4. Silty soil


Correct Option: A
Explanation:

Sandy soil is most susceptible to wind erosion because it is composed of loose, fine particles that are easily carried away by the wind.

The process of soil erosion by water is known as:

  1. Sheet erosion

  2. Rill erosion

  3. Gully erosion

  4. All of the above


Correct Option: D
Explanation:

Sheet erosion, rill erosion, and gully erosion are all types of soil erosion caused by water.

Which of the following is NOT a consequence of soil erosion?

  1. Loss of soil fertility

  2. Increased flooding

  3. Desertification

  4. Improved water quality


Correct Option: D
Explanation:

Soil erosion can lead to a loss of soil fertility, increased flooding, and desertification, but it does not improve water quality.

Contour plowing is a farming practice that helps reduce soil erosion by:

  1. Creating ridges and furrows that slow down the flow of water

  2. Increasing the infiltration of water into the soil

  3. Reducing the amount of runoff from the land

  4. All of the above


Correct Option: D
Explanation:

Contour plowing helps reduce soil erosion by creating ridges and furrows that slow down the flow of water, increasing the infiltration of water into the soil, and reducing the amount of runoff from the land.

Which of the following is NOT a measure that can be taken to control soil erosion?

  1. Reforestation

  2. Terracing

  3. Contour plowing

  4. Burning crop residues


Correct Option: D
Explanation:

Burning crop residues can increase soil erosion by removing the protective cover of vegetation and exposing the soil to the elements.

The process of soil erosion by gravity is known as:

  1. Creep

  2. Slump

  3. Earthflow

  4. All of the above


Correct Option: D
Explanation:

Creep, slump, and earthflow are all types of soil erosion caused by gravity.

Which of the following is NOT a factor that influences the rate of soil erosion by water?

  1. Rainfall intensity

  2. Slope of the land

  3. Soil texture

  4. Wind speed


Correct Option: D
Explanation:

Wind speed is not a factor that influences the rate of soil erosion by water.

Terracing is a farming practice that helps reduce soil erosion by:

  1. Creating level strips of land across the slope

  2. Slowing down the flow of water

  3. Increasing the infiltration of water into the soil

  4. All of the above


Correct Option: D
Explanation:

Terracing helps reduce soil erosion by creating level strips of land across the slope, slowing down the flow of water, and increasing the infiltration of water into the soil.

Which of the following is NOT a consequence of deforestation?

  1. Increased soil erosion

  2. Loss of biodiversity

  3. Climate change

  4. Improved water quality


Correct Option: D
Explanation:

Deforestation can lead to increased soil erosion, loss of biodiversity, and climate change, but it does not improve water quality.

The process of soil erosion by ice is known as:

  1. Glacial erosion

  2. Periglacial erosion

  3. Solifluction

  4. All of the above


Correct Option: D
Explanation:

Glacial erosion, periglacial erosion, and solifluction are all types of soil erosion caused by ice.

Which of the following is NOT a measure that can be taken to control soil erosion by wind?

  1. Planting windbreaks

  2. Using mulches

  3. Contour plowing

  4. Burning crop residues


Correct Option: C
Explanation:

Contour plowing is not a measure that can be taken to control soil erosion by wind.
