What is the primary objective of land and water conservation?

  1. To increase agricultural productivity

  2. To prevent soil erosion and degradation

  3. To manage water resources efficiently

  4. To enhance biodiversity and ecosystem services


Correct Option: B
Explanation:

Land and water conservation aims to protect soil from erosion, maintain soil fertility, and prevent water quality degradation.

Which of the following is NOT a common soil conservation practice?

  1. Contour plowing

  2. Terracing

  3. Crop rotation

  4. Clear-cutting


Correct Option: D
Explanation:

Clear-cutting is a forestry practice that involves removing all trees from a forest area, which can lead to soil erosion and degradation.

What is the purpose of contour plowing?

  1. To reduce soil erosion

  2. To improve water infiltration

  3. To control weeds and pests

  4. To increase crop yields


Correct Option: A
Explanation:

Contour plowing is a farming technique that involves plowing along the contour lines of a slope, which helps to slow down water runoff and reduce soil erosion.

Which of the following is a type of water conservation practice?

  1. Drip irrigation

  2. Rainwater harvesting

  3. Flood irrigation

  4. Sprinkler irrigation


Correct Option: A
Explanation:

Drip irrigation is a water-efficient irrigation method that delivers water directly to the roots of plants, minimizing water loss through evaporation and runoff.

What is the primary cause of soil erosion?

  1. Wind

  2. Water

  3. Gravity

  4. Human activities


Correct Option: B
Explanation:

Water erosion is the primary cause of soil erosion, as water runoff can carry away soil particles, especially on sloping land.

Which of the following is a benefit of crop rotation?

  1. It helps control pests and diseases

  2. It improves soil fertility

  3. It reduces the risk of soil erosion

  4. All of the above


Correct Option: D
Explanation:

Crop rotation is a farming practice that involves growing different crops in the same area in sequential seasons, which helps control pests and diseases, improves soil fertility, and reduces the risk of soil erosion.

What is the term for the process of planting trees or other vegetation to help prevent soil erosion?

  1. Reforestation

  2. Afforestation

  3. Erosion control

  4. Soil conservation


Correct Option: B
Explanation:

Afforestation is the process of planting trees or other vegetation in an area that was previously devoid of trees, typically to help prevent soil erosion and improve the environment.

Which of the following is an example of a non-point source of water pollution?

  1. Industrial wastewater discharge

  2. Fertilizer runoff from farms

  3. Sewage treatment plant discharge

  4. Oil spills


Correct Option: B
Explanation:

Non-point source pollution refers to pollution that does not originate from a single, identifiable source, such as fertilizer runoff from farms, which can contribute to water quality degradation.

What is the primary goal of watershed management?

  1. To protect water quality

  2. To prevent flooding

  3. To conserve soil and water resources

  4. To promote sustainable land use practices


Correct Option: C
Explanation:

Watershed management aims to conserve soil and water resources, protect water quality, prevent flooding, and promote sustainable land use practices within a watershed.

Which of the following is a type of sustainable land use practice?

  1. Monoculture farming

  2. Slash-and-burn agriculture

  3. Contour farming

  4. Clear-cutting


Correct Option: C
Explanation:

Contour farming is a sustainable land use practice that involves farming along the contour lines of a slope, which helps reduce soil erosion and conserve water.

What is the term for the process of removing excess water from soil?

  1. Drainage

  2. Irrigation

  3. Evaporation

  4. Transpiration


Correct Option: A
Explanation:

Drainage is the process of removing excess water from soil, typically through the use of ditches, tiles, or other drainage systems.

Which of the following is NOT a benefit of wetlands?

  1. They provide habitat for wildlife

  2. They help control flooding

  3. They filter pollutants from water

  4. They contribute to climate change


Correct Option: D
Explanation:

Wetlands provide numerous benefits, including wildlife habitat, flood control, and water filtration, but they do not contribute to climate change.

What is the term for the process of converting forest land to non-forest land?

  1. Deforestation

  2. Reforestation

  3. Afforestation

  4. Erosion control


Correct Option: A
Explanation:

Deforestation refers to the process of converting forest land to non-forest land, typically for agriculture, development, or other purposes.

Which of the following is a type of soil conservation structure?

  1. Terraces

  2. Contour bunds

  3. Check dams

  4. All of the above


Correct Option: D
Explanation:

Terraces, contour bunds, and check dams are all types of soil conservation structures used to reduce soil erosion and conserve water.

What is the term for the process of managing water resources in a sustainable manner?

  1. Water conservation

  2. Water management

  3. Watershed management

  4. Aquifer recharge


Correct Option: B
Explanation:

Water management refers to the process of managing water resources in a sustainable manner, including water conservation, watershed management, and aquifer recharge.
