What is the primary cause of deforestation globally?

  1. Natural Disasters

  2. Agricultural Expansion

  3. Urbanization

  4. Forest Fires


Correct Option: B
Explanation:

Agricultural expansion, driven by the increasing demand for food and other agricultural products, is the leading cause of deforestation worldwide.

Which of these is NOT a direct consequence of deforestation?

  1. Loss of Biodiversity

  2. Soil Erosion

  3. Increased Carbon Sequestration

  4. Climate Change


Correct Option: C
Explanation:

Deforestation leads to the release of carbon dioxide into the atmosphere, contributing to climate change. It does not result in increased carbon sequestration.

How does deforestation impact the water cycle?

  1. It increases water infiltration and groundwater recharge.

  2. It reduces water evaporation and humidity.

  3. It leads to more frequent and severe droughts.

  4. It enhances water quality and reduces pollution.


Correct Option: C
Explanation:

Deforestation disrupts the water cycle, leading to reduced water infiltration, increased runoff, and more frequent and severe droughts.

Which of these is a potential solution to mitigate the environmental impact of deforestation?

  1. Promoting Sustainable Agriculture Practices

  2. Implementing Reforestation and Afforestation Programs

  3. Encouraging the Use of Renewable Energy Sources

  4. All of the Above


Correct Option: D
Explanation:

A combination of sustainable agriculture practices, reforestation and afforestation programs, and the promotion of renewable energy sources can help mitigate the environmental impact of deforestation.

What is the term used to describe the conversion of forest land to non-forest uses, such as agriculture, urbanization, or mining?

  1. Deforestation

  2. Land Degradation

  3. Land Use Change

  4. Habitat Fragmentation


Correct Option: C
Explanation:

Land use change refers to the conversion of forest land to other non-forest uses, resulting in the loss of forest cover.

Which of these is NOT a consequence of habitat fragmentation caused by deforestation?

  1. Increased Genetic Diversity

  2. Reduced Population Connectivity

  3. Loss of Ecosystem Services

  4. Increased Risk of Extinction


Correct Option: A
Explanation:

Habitat fragmentation due to deforestation leads to reduced genetic diversity, increased risk of extinction, and loss of ecosystem services. It does not result in increased genetic diversity.

How does deforestation contribute to climate change?

  1. It releases carbon dioxide into the atmosphere.

  2. It reduces the Earth's albedo.

  3. It disrupts the global water cycle.

  4. All of the Above


Correct Option: D
Explanation:

Deforestation contributes to climate change by releasing carbon dioxide into the atmosphere, reducing the Earth's albedo, and disrupting the global water cycle.

Which of these is NOT a potential impact of deforestation on biodiversity?

  1. Loss of Habitat and Species Extinction

  2. Reduced Genetic Diversity

  3. Increased Ecosystem Resilience

  4. Disruption of Ecological Interactions


Correct Option: C
Explanation:

Deforestation negatively impacts biodiversity by causing habitat loss, species extinction, reduced genetic diversity, and disruption of ecological interactions. It does not lead to increased ecosystem resilience.

What is the term used to describe the process of planting trees on land that was previously deforested or degraded?

  1. Reforestation

  2. Afforestation

  3. Rehabilitation

  4. Restoration


Correct Option: A
Explanation:

Reforestation refers to the process of planting trees on land that was previously deforested or degraded, with the aim of restoring forest cover and ecosystem function.

Which of these is NOT a potential consequence of soil erosion caused by deforestation?

  1. Loss of Soil Fertility

  2. Increased Water Pollution

  3. Enhanced Soil Biodiversity

  4. Reduced Landslides and Mudslides


Correct Option: C
Explanation:

Soil erosion caused by deforestation leads to loss of soil fertility, increased water pollution, and increased risk of landslides and mudslides. It does not result in enhanced soil biodiversity.

How does deforestation impact the livelihoods of indigenous communities and local populations?

  1. It disrupts traditional practices and cultural identity.

  2. It reduces access to natural resources and food security.

  3. It leads to displacement and loss of ancestral lands.

  4. All of the Above


Correct Option: D
Explanation:

Deforestation can have significant negative impacts on indigenous communities and local populations, including disruption of traditional practices and cultural identity, reduced access to natural resources and food security, and displacement and loss of ancestral lands.

Which of these is NOT a potential strategy for reducing deforestation and promoting sustainable land use?

  1. Implementing Payment for Ecosystem Services (PES) Schemes

  2. Promoting Agroforestry and Sustainable Agriculture Practices

  3. Encouraging the Use of Genetically Modified Crops

  4. Supporting Community-Based Forest Management


Correct Option: C
Explanation:

While implementing PES schemes, promoting agroforestry and sustainable agriculture practices, and supporting community-based forest management are strategies for reducing deforestation, encouraging the use of genetically modified crops is not directly related to this goal.

What is the term used to describe the process of restoring degraded or damaged forest ecosystems to their natural state?

  1. Reforestation

  2. Afforestation

  3. Rehabilitation

  4. Restoration


Correct Option: D
Explanation:

Restoration refers to the process of restoring degraded or damaged forest ecosystems to their natural state, involving the reestablishment of native species and ecological functions.

Which of these is NOT a potential impact of deforestation on water quality?

  1. Increased Sedimentation and Turbidity

  2. Elevated Nutrient Levels and Eutrophication

  3. Improved Water Clarity and Dissolved Oxygen Levels

  4. Increased Risk of Waterborne Diseases


Correct Option: C
Explanation:

Deforestation can lead to increased sedimentation and turbidity, elevated nutrient levels and eutrophication, and increased risk of waterborne diseases. It does not result in improved water clarity and dissolved oxygen levels.

How does deforestation contribute to the loss of biodiversity?

  1. It reduces habitat availability and connectivity.

  2. It disrupts ecological interactions and food webs.

  3. It leads to the extinction of species and genetic diversity.

  4. All of the Above


Correct Option: D
Explanation:

Deforestation contributes to the loss of biodiversity by reducing habitat availability and connectivity, disrupting ecological interactions and food webs, and leading to the extinction of species and genetic diversity.
