What is the primary cause of deforestation?

  1. Natural disasters

  2. Agricultural expansion

  3. Urbanization

  4. Climate change


Correct Option: B
Explanation:

Agricultural expansion, particularly for large-scale farming and plantations, is the leading cause of deforestation worldwide.

Which of the following is a direct consequence of deforestation?

  1. Increased carbon sequestration

  2. Enhanced water retention

  3. Reduced soil erosion

  4. Loss of biodiversity


Correct Option: D
Explanation:

Deforestation results in the loss of habitats and ecosystems, leading to a decline in biodiversity and species extinction.

How does deforestation affect the water cycle?

  1. It increases water infiltration and groundwater recharge.

  2. It reduces surface runoff and flooding.

  3. It enhances water purification and quality.

  4. It disrupts the water cycle, leading to droughts and floods.


Correct Option: D
Explanation:

Deforestation alters the water cycle by reducing water infiltration, increasing surface runoff, and disrupting the balance between evaporation and precipitation.

What is the primary greenhouse gas released during deforestation?

  1. Oxygen

  2. Carbon dioxide

  3. Nitrogen

  4. Methane


Correct Option: B
Explanation:

Deforestation releases large amounts of carbon dioxide into the atmosphere through the burning and decomposition of forest biomass, contributing to climate change.

Which of the following is a consequence of soil erosion caused by deforestation?

  1. Improved soil fertility

  2. Enhanced water retention

  3. Increased crop yields

  4. Loss of soil nutrients and productivity


Correct Option: D
Explanation:

Deforestation leads to soil erosion, which removes the fertile topsoil and essential nutrients, resulting in reduced soil productivity and agricultural yields.

How does deforestation impact the livelihoods of indigenous communities?

  1. It improves their access to healthcare and education.

  2. It enhances their economic opportunities.

  3. It strengthens their cultural identity and traditions.

  4. It disrupts their traditional way of life and livelihoods.


Correct Option: D
Explanation:

Deforestation often disrupts the traditional way of life and livelihoods of indigenous communities who rely on forests for food, shelter, medicine, and cultural practices.

What is the term used to describe the conversion of forest land to other uses, such as agriculture or development?

  1. Reforestation

  2. Afforestation

  3. Deforestation

  4. Land conversion


Correct Option: D
Explanation:

Land conversion refers to the process of changing the use of land from one purpose to another, often involving the conversion of forest land to other uses.

Which of the following is a potential consequence of land use changes, including deforestation?

  1. Increased biodiversity

  2. Enhanced carbon sequestration

  3. Improved water quality

  4. Habitat fragmentation and loss


Correct Option: D
Explanation:

Land use changes, including deforestation, can lead to habitat fragmentation and loss, which negatively impacts biodiversity and ecosystem functioning.

How does deforestation contribute to climate change?

  1. It reduces the release of greenhouse gases.

  2. It enhances the absorption of carbon dioxide.

  3. It increases the Earth's albedo.

  4. It releases carbon dioxide and reduces carbon sinks.


Correct Option: D
Explanation:

Deforestation releases carbon dioxide into the atmosphere and reduces the capacity of forests to absorb carbon dioxide, contributing to climate change.

Which of the following is a potential strategy to mitigate the negative consequences of deforestation?

  1. Promoting sustainable agriculture practices

  2. Implementing reforestation and afforestation programs

  3. Reducing the demand for wood and wood products

  4. All of the above


Correct Option: D
Explanation:

Mitigating the negative consequences of deforestation requires a combination of strategies, including promoting sustainable agriculture practices, implementing reforestation and afforestation programs, and reducing the demand for wood and wood products.
