Which of the following is NOT a primary cause of soil erosion?

  1. Wind

  2. Water

  3. Deforestation

  4. Crop Rotation


Correct Option: D
Explanation:

Crop rotation is a sustainable land management practice that helps maintain soil health and reduce erosion, rather than being a primary cause of it.

What is the process by which soil is transported from one place to another?

  1. Weathering

  2. Erosion

  3. Leaching

  4. Deposition


Correct Option: B
Explanation:

Erosion is the process by which soil is detached and transported from one place to another by wind, water, or other natural forces.

Which of the following is NOT a type of water pollution caused by agricultural activities?

  1. Nutrient Pollution

  2. Pesticide Pollution

  3. Erosion

  4. Salinization


Correct Option: C
Explanation:

Erosion is a process that occurs naturally, while nutrient pollution, pesticide pollution, and salinization are all types of water pollution caused by agricultural activities.

What is the practice of planting different crops in a sequence on the same land over time called?

  1. Monoculture

  2. Crop Rotation

  3. Fallowing

  4. Contour Farming


Correct Option: B
Explanation:

Crop rotation is the practice of planting different crops in a sequence on the same land over time to improve soil health, reduce erosion, and control pests and diseases.

Which of the following is NOT a sustainable land management practice?

  1. Contour Farming

  2. Terracing

  3. Monoculture

  4. Cover Cropping


Correct Option: C
Explanation:

Monoculture, the practice of growing a single crop on the same land year after year, is not considered a sustainable land management practice due to its negative impacts on soil health and increased susceptibility to pests and diseases.

What is the process by which water moves through the soil profile?

  1. Infiltration

  2. Runoff

  3. Percolation

  4. Evaporation


Correct Option: A
Explanation:

Infiltration is the process by which water moves through the soil profile, entering the ground and becoming part of the soil water.

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

  1. Sheet Erosion

  2. Rill Erosion

  3. Gully Erosion

  4. Wind Erosion


Correct Option: D
Explanation:

Wind erosion is a type of soil erosion caused by the force of wind, while sheet erosion, rill erosion, and gully erosion are all types of soil erosion caused by water.

What is the practice of farming along the contours of a slope to reduce erosion called?

  1. Contour Farming

  2. Terracing

  3. Strip Cropping

  4. Fallowing


Correct Option: A
Explanation:

Contour farming is the practice of farming along the contours of a slope to reduce erosion by slowing down the flow of water and allowing it to soak into the soil.

Which of the following is NOT a type of water pollution caused by urban activities?

  1. Sewage Pollution

  2. Industrial Pollution

  3. Erosion

  4. Stormwater Runoff


Correct Option: C
Explanation:

Erosion is a process that occurs naturally, while sewage pollution, industrial pollution, and stormwater runoff are all types of water pollution caused by urban activities.

What is the practice of leaving a field fallow for a period of time to restore soil health and fertility called?

  1. Monoculture

  2. Crop Rotation

  3. Fallowing

  4. Contour Farming


Correct Option: C
Explanation:

Fallowing is the practice of leaving a field fallow for a period of time to restore soil health and fertility, allowing the soil to rest and rebuild its nutrient reserves.

Which of the following is NOT a benefit of sustainable land management practices?

  1. Reduced Soil Erosion

  2. Improved Water Quality

  3. Increased Crop Yields

  4. Increased Deforestation


Correct Option: D
Explanation:

Sustainable land management practices aim to reduce soil erosion, improve water quality, and increase crop yields, while deforestation is a harmful practice that leads to soil degradation and loss of biodiversity.

What is the process by which water evaporates from the soil surface and returns to the atmosphere called?

  1. Infiltration

  2. Runoff

  3. Percolation

  4. Evaporation


Correct Option: D
Explanation:

Evaporation is the process by which water evaporates from the soil surface and returns to the atmosphere, contributing to the water cycle.

Which of the following is NOT a type of soil conservation structure?

  1. Contour Bunds

  2. Terraces

  3. Windbreaks

  4. Crop Rotation


Correct Option: D
Explanation:

Crop rotation is a sustainable land management practice, while contour bunds, terraces, and windbreaks are all types of soil conservation structures designed to reduce erosion and improve soil health.

What is the practice of planting trees and shrubs in rows to reduce wind erosion called?

  1. Contour Farming

  2. Terracing

  3. Strip Cropping

  4. Windbreaks


Correct Option: D
Explanation:

Windbreaks are rows of trees and shrubs planted to reduce wind erosion and protect soil and crops from strong winds.

Which of the following is NOT a type of water pollution caused by agricultural activities?

  1. Nutrient Pollution

  2. Pesticide Pollution

  3. Erosion

  4. Salinization


Correct Option: C
Explanation:

Erosion is a process that occurs naturally, while nutrient pollution, pesticide pollution, and salinization are all types of water pollution caused by agricultural activities.
