Which of the following is a primary cause of deforestation?

  1. Natural disasters

  2. Agricultural expansion

  3. Urban development

  4. Forest fires


Correct Option: B
Explanation:

Agricultural expansion, particularly for large-scale farming, is a major driver of deforestation as forests are cleared to make way for crops and livestock.

What percentage of the Earth's land surface is covered by forests?

  1. 20%

  2. 30%

  3. 40%

  4. 50%


Correct Option: B
Explanation:

Approximately 30% of the Earth's land surface is covered by forests, playing a crucial role in the global ecosystem.

Which of the following is a sustainable forestry practice?

  1. Clear-cutting

  2. Selective logging

  3. Monoculture plantations

  4. Forest fragmentation


Correct Option: B
Explanation:

Selective logging involves harvesting mature trees while preserving the overall forest structure and biodiversity, ensuring the long-term sustainability of the forest.

What is the primary role of forests in climate change mitigation?

  1. Releasing oxygen into the atmosphere

  2. Absorbing carbon dioxide

  3. Producing renewable energy

  4. Preventing soil erosion


Correct Option: B
Explanation:

Forests act as carbon sinks, absorbing carbon dioxide from the atmosphere and storing it in their biomass, thus reducing greenhouse gas concentrations.

Which of the following is a consequence of deforestation?

  1. Increased biodiversity

  2. Reduced soil erosion

  3. Enhanced water quality

  4. Climate change


Correct Option: D
Explanation:

Deforestation contributes to climate change by releasing stored carbon into the atmosphere and reducing the Earth's capacity to absorb carbon dioxide.

What is the term for the conversion of forest land to non-forest uses?

  1. Reforestation

  2. Deforestation

  3. Afforestation

  4. Agroforestry


Correct Option: B
Explanation:

Deforestation refers to the permanent removal of forest cover, typically for agricultural, industrial, or urban development.

Which of the following is an example of a non-timber forest product?

  1. Honey

  2. Timber

  3. Pulpwood

  4. Firewood


Correct Option: A
Explanation:

Non-timber forest products are goods derived from forests other than timber, such as honey, fruits, nuts, and medicinal plants.

What is the primary cause of forest fires?

  1. Lightning strikes

  2. Human activities

  3. Droughts

  4. Volcanic eruptions


Correct Option: B
Explanation:

Human activities, such as campfires left unattended, arson, and accidental ignitions, are the leading cause of forest fires.

Which of the following is a benefit of agroforestry?

  1. Increased soil erosion

  2. Reduced biodiversity

  3. Enhanced water quality

  4. Deforestation


Correct Option: C
Explanation:

Agroforestry practices, such as integrating trees into agricultural systems, can improve water quality by reducing runoff and filtering pollutants.

What is the term for the process of planting trees in areas that were previously not forested?

  1. Reforestation

  2. Deforestation

  3. Afforestation

  4. Agroforestry


Correct Option: C
Explanation:

Afforestation refers to the establishment of forests on land that was not previously forested.

Which of the following is a sustainable land use practice?

  1. Monoculture farming

  2. Slash-and-burn agriculture

  3. Crop rotation

  4. Excessive use of pesticides


Correct Option: C
Explanation:

Crop rotation, the practice of growing different crops in the same area in sequential seasons, helps maintain soil fertility and reduce the risk of pests and diseases.

What is the primary cause of soil erosion?

  1. Wind

  2. Water

  3. Deforestation

  4. Agricultural practices


Correct Option: D
Explanation:

Agricultural practices, such as intensive tillage and overgrazing, can accelerate soil erosion by removing vegetation cover and exposing the soil to wind and water.

Which of the following is a benefit of forest conservation?

  1. Increased greenhouse gas emissions

  2. Reduced biodiversity

  3. Enhanced water quality

  4. Deforestation


Correct Option: C
Explanation:

Forest conservation helps maintain water quality by regulating water flow, reducing erosion, and filtering pollutants.

What is the term for the process of restoring degraded or damaged forests to their natural state?

  1. Reforestation

  2. Deforestation

  3. Afforestation

  4. Forest restoration


Correct Option: D
Explanation:

Forest restoration involves restoring degraded or damaged forests to their natural state through various techniques such as planting trees, controlling invasive species, and managing fire.

Which of the following is a sustainable forestry practice?

  1. Clear-cutting

  2. Selective logging

  3. Monoculture plantations

  4. Forest fragmentation


Correct Option: B
Explanation:

Selective logging involves harvesting mature trees while preserving the overall forest structure and biodiversity, ensuring the long-term sustainability of the forest.
