Which of the following is a primary source of water in deserts?

  1. Groundwater

  2. Surface water

  3. Rainwater

  4. Desalination


Correct Option: A
Explanation:

Groundwater is the primary source of water in deserts, as it is stored beneath the surface and can be accessed through wells or boreholes.

What is the process of removing salt from seawater to make it drinkable called?

  1. Desalination

  2. Filtration

  3. Reverse osmosis

  4. Distillation


Correct Option: A
Explanation:

Desalination is the process of removing salt from seawater to make it drinkable. This can be done through various methods, including reverse osmosis and distillation.

Which of the following is a traditional method of collecting rainwater in deserts?

  1. Fog nets

  2. Cisterns

  3. Wells

  4. Aquifers


Correct Option: B
Explanation:

Cisterns are traditional underground storage tanks used to collect and store rainwater in deserts. They are typically made of stone, concrete, or metal.

What is the name of the technique that involves planting trees in rows to slow down wind speed and reduce soil erosion in deserts?

  1. Contour plowing

  2. Windbreaks

  3. Terracing

  4. Mulching


Correct Option: B
Explanation:

Windbreaks are rows of trees or shrubs planted to slow down wind speed and reduce soil erosion in deserts. They help to trap wind-blown sand and create a more favorable microclimate for plant growth.

Which of the following is a challenge associated with water scarcity in deserts?

  1. Increased agricultural productivity

  2. Desertification

  3. Improved public health

  4. Economic development


Correct Option: B
Explanation:

Water scarcity in deserts can lead to desertification, which is the process of land degradation in arid and semi-arid regions. Desertification can result in the loss of vegetation, soil erosion, and the displacement of people.

What is the name of the process by which water vapor in the air condenses on cool surfaces in deserts?

  1. Evaporation

  2. Condensation

  3. Precipitation

  4. Transpiration


Correct Option: B
Explanation:

Condensation is the process by which water vapor in the air condenses on cool surfaces in deserts. This can occur on rocks, plants, or even human skin.

Which of the following is a type of fog-collecting net used to capture water droplets in deserts?

  1. Windsock

  2. Barbed wire

  3. Fog fence

  4. Anemometer


Correct Option: C
Explanation:

Fog fences are large nets used to capture water droplets from fog in deserts. They are typically made of plastic or nylon mesh and can collect significant amounts of water.

What is the name of the process by which plants release water vapor into the atmosphere?

  1. Evaporation

  2. Transpiration

  3. Condensation

  4. Precipitation


Correct Option: B
Explanation:

Transpiration is the process by which plants release water vapor into the atmosphere through their leaves. This process helps to regulate the plant's temperature and contributes to the water cycle.

Which of the following is a type of underground water storage system used in deserts?

  1. Aquifer

  2. Cistern

  3. Well

  4. Reservoir


Correct Option: A
Explanation:

An aquifer is an underground layer of rock or soil that contains water. Aquifers are important sources of water in deserts, as they can store large amounts of water that can be accessed through wells or boreholes.

What is the name of the technique that involves digging shallow pits in the desert to collect rainwater?

  1. Contour plowing

  2. Terracing

  3. Mulching

  4. Zai pits


Correct Option: D
Explanation:

Zai pits are shallow pits dug in the desert to collect rainwater. They are typically filled with organic matter, such as manure or compost, to help retain moisture and improve soil fertility.

Which of the following is a type of water-efficient irrigation system used in deserts?

  1. Drip irrigation

  2. Sprinkler irrigation

  3. Flood irrigation

  4. Furrow irrigation


Correct Option: A
Explanation:

Drip irrigation is a water-efficient irrigation system that delivers water directly to the roots of plants through a network of pipes and emitters. This method reduces water evaporation and helps to conserve water.

What is the name of the process by which water is removed from the soil by evaporation and plant transpiration?

  1. Evapotranspiration

  2. Condensation

  3. Precipitation

  4. Infiltration


Correct Option: A
Explanation:

Evapotranspiration is the process by which water is removed from the soil by evaporation and plant transpiration. This process is important for the water cycle and helps to regulate the Earth's climate.

Which of the following is a type of plant that is adapted to survive in desert conditions?

  1. Xerophytes

  2. Hydrophytes

  3. Mesophytes

  4. Hygrophytes


Correct Option: A
Explanation:

Xerophytes are plants that are adapted to survive in desert conditions. They have various adaptations, such as thick cuticles, reduced leaves, and deep roots, that help them to conserve water and survive in arid environments.

What is the name of the process by which water is stored in the soil?

  1. Infiltration

  2. Evaporation

  3. Condensation

  4. Precipitation


Correct Option: A
Explanation:

Infiltration is the process by which water is stored in the soil. This process occurs when water from the surface seeps into the soil through pores and cracks.
