Which of the following is NOT a direct impact of deforestation on water resources?

  1. Increased surface runoff

  2. Reduced groundwater recharge

  3. Improved water quality

  4. Increased soil erosion


Correct Option: C
Explanation:

Deforestation leads to increased surface runoff, reduced groundwater recharge, and increased soil erosion, all of which can negatively impact water quality.

How does deforestation affect the water cycle?

  1. It increases evapotranspiration.

  2. It decreases precipitation.

  3. It increases cloud formation.

  4. It decreases humidity.


Correct Option: A
Explanation:

Deforestation reduces the amount of vegetation that transpires water vapor into the atmosphere, leading to decreased evapotranspiration and a drier climate.

Which of the following is NOT a consequence of reduced groundwater recharge due to deforestation?

  1. Lower water tables

  2. Increased risk of droughts

  3. Reduced streamflow

  4. Improved water quality


Correct Option: D
Explanation:

Reduced groundwater recharge can lead to lower water tables, increased risk of droughts, and reduced streamflow, all of which can negatively impact water quality.

How does deforestation affect soil erosion?

  1. It increases soil erosion.

  2. It decreases soil erosion.

  3. It has no effect on soil erosion.

  4. It reverses soil erosion.


Correct Option: A
Explanation:

Deforestation removes the protective cover of vegetation from the soil, making it more susceptible to erosion by wind and water.

Which of the following is NOT a potential impact of increased soil erosion due to deforestation?

  1. Sedimentation of water bodies

  2. Loss of soil fertility

  3. Improved water quality

  4. Increased flooding


Correct Option: C
Explanation:

Increased soil erosion can lead to sedimentation of water bodies, loss of soil fertility, and increased flooding, all of which can negatively impact water quality.

How does deforestation affect the water quality of rivers and streams?

  1. It improves water quality.

  2. It degrades water quality.

  3. It has no effect on water quality.

  4. It improves water quality in some cases and degrades it in others.


Correct Option: B
Explanation:

Deforestation can lead to increased sediment loads, nutrient pollution, and higher water temperatures, all of which can degrade water quality.

Which of the following is NOT a potential consequence of degraded water quality due to deforestation?

  1. Increased risk of waterborne diseases

  2. Reduced biodiversity

  3. Improved fisheries productivity

  4. Increased recreational opportunities


Correct Option: D
Explanation:

Degraded water quality can lead to increased risk of waterborne diseases, reduced biodiversity, and decreased recreational opportunities.

How does deforestation affect the water supply for human populations?

  1. It increases the water supply.

  2. It decreases the water supply.

  3. It has no effect on the water supply.

  4. It increases the water supply in some cases and decreases it in others.


Correct Option: B
Explanation:

Deforestation can lead to reduced groundwater recharge, decreased streamflow, and increased water pollution, all of which can reduce the water supply for human populations.

Which of the following is NOT a potential impact of reduced water supply due to deforestation?

  1. Increased competition for water resources

  2. Reduced agricultural productivity

  3. Improved hydropower generation

  4. Increased risk of water conflicts


Correct Option: C
Explanation:

Reduced water supply can lead to increased competition for water resources, reduced agricultural productivity, and increased risk of water conflicts.

What are some of the potential solutions to address the impacts of deforestation on water resources?

  1. Reforestation and afforestation

  2. Sustainable forest management

  3. Water conservation measures

  4. All of the above


Correct Option: D
Explanation:

Reforestation and afforestation, sustainable forest management, and water conservation measures are all important strategies to address the impacts of deforestation on water resources.

Which of the following is NOT a benefit of reforestation and afforestation in terms of water resources?

  1. Increased groundwater recharge

  2. Reduced soil erosion

  3. Improved water quality

  4. Increased water consumption


Correct Option: D
Explanation:

Reforestation and afforestation can help to increase groundwater recharge, reduce soil erosion, and improve water quality, but they do not increase water consumption.

How does sustainable forest management help to protect water resources?

  1. It minimizes soil erosion.

  2. It maintains forest cover.

  3. It reduces water pollution.

  4. All of the above


Correct Option: D
Explanation:

Sustainable forest management practices such as selective logging, reforestation, and erosion control help to minimize soil erosion, maintain forest cover, and reduce water pollution.

What are some examples of water conservation measures that can help to mitigate the impacts of deforestation?

  1. Drip irrigation

  2. Rainwater harvesting

  3. Water-efficient landscaping

  4. All of the above


Correct Option: D
Explanation:

Drip irrigation, rainwater harvesting, and water-efficient landscaping are all examples of water conservation measures that can help to reduce water consumption and mitigate the impacts of deforestation on water resources.

Why is it important to address the impacts of deforestation on water resources?

  1. Water is essential for life.

  2. Deforestation is a major threat to water resources.

  3. The impacts of deforestation on water resources are far-reaching.

  4. All of the above


Correct Option: D
Explanation:

Water is essential for life, deforestation is a major threat to water resources, and the impacts of deforestation on water resources are far-reaching, affecting human populations, ecosystems, and the global climate.
