What is the primary role of forests in the global carbon cycle?

  1. Carbon emission

  2. Carbon storage

  3. Carbon release

  4. Carbon transformation


Correct Option: B
Explanation:

Forests act as carbon sinks, absorbing carbon dioxide from the atmosphere and storing it in their biomass and soil.

Which process is responsible for the removal of carbon dioxide from the atmosphere by forests?

  1. Photosynthesis

  2. Cellular respiration

  3. Decomposition

  4. Transpiration


Correct Option: A
Explanation:

During photosynthesis, trees and other plants use sunlight to convert carbon dioxide and water into glucose and oxygen, storing carbon in their tissues.

What is the term used to describe the long-term storage of carbon in forests?

  1. Carbon sequestration

  2. Carbon capture

  3. Carbon fixation

  4. Carbon sink


Correct Option: A
Explanation:

Carbon sequestration refers to the process by which forests absorb and store carbon dioxide from the atmosphere, reducing the levels of greenhouse gases.

Which type of forest is generally considered to be the most effective in carbon sequestration?

  1. Tropical rainforests

  2. Temperate forests

  3. Boreal forests

  4. Mangrove forests


Correct Option: A
Explanation:

Tropical rainforests are known for their high rates of carbon sequestration due to their rapid growth, diverse vegetation, and favorable climatic conditions.

How does deforestation contribute to climate change?

  1. It reduces carbon sequestration

  2. It releases stored carbon

  3. It increases oxygen levels

  4. It enhances biodiversity


Correct Option:
Explanation:

Deforestation not only reduces the capacity of forests to absorb carbon dioxide but also releases the carbon stored in trees and soil, contributing to the increase in greenhouse gas concentrations.

What is the primary mechanism by which forests regulate the Earth's climate?

  1. Carbon sequestration

  2. Water cycle regulation

  3. Temperature regulation

  4. Nutrient cycling


Correct Option: A
Explanation:

Forests play a crucial role in regulating the Earth's climate primarily through carbon sequestration, which helps mitigate the effects of greenhouse gases and stabilize global temperatures.

How does the loss of forest cover impact the local climate?

  1. Increased rainfall

  2. Decreased humidity

  3. Higher temperatures

  4. Reduced wind speed


Correct Option: C
Explanation:

Deforestation can lead to an increase in local temperatures due to the loss of shade and evapotranspiration, resulting in a warmer and drier microclimate.

Which international agreement aims to reduce emissions from deforestation and forest degradation?

  1. Kyoto Protocol

  2. Paris Agreement

  3. Montreal Protocol

  4. Copenhagen Accord


Correct Option: B
Explanation:

The Paris Agreement includes a specific goal to reduce emissions from deforestation and forest degradation, recognizing the importance of forests in climate change mitigation.

What is the term used to describe the process of increasing the carbon storage capacity of forests?

  1. Reforestation

  2. Afforestation

  3. Carbon fertilization

  4. Agroforestry


Correct Option: B
Explanation:

Afforestation refers to the establishment of forests on land that was previously not forested, thereby increasing the carbon storage capacity of the area.

How does sustainable forest management contribute to climate change mitigation?

  1. It reduces deforestation

  2. It enhances carbon sequestration

  3. It promotes biodiversity conservation

  4. All of the above


Correct Option: D
Explanation:

Sustainable forest management practices aim to reduce deforestation, enhance carbon sequestration, and promote biodiversity conservation, all of which contribute to climate change mitigation.

Which forest management practice is commonly used to increase carbon sequestration in managed forests?

  1. Clear-cutting

  2. Selective logging

  3. Coppicing

  4. Thinning


Correct Option: B
Explanation:

Selective logging involves the removal of selected trees while leaving the majority of the forest intact, allowing for continued carbon sequestration and minimizing the impact on the ecosystem.

What is the role of agroforestry in carbon sequestration?

  1. It integrates trees into agricultural systems

  2. It enhances soil carbon storage

  3. It reduces deforestation pressure

  4. All of the above


Correct Option: D
Explanation:

Agroforestry practices integrate trees into agricultural systems, enhancing soil carbon storage, reducing deforestation pressure, and contributing to overall carbon sequestration.

How does forest restoration contribute to climate change mitigation?

  1. It increases carbon sequestration

  2. It reduces greenhouse gas emissions

  3. It enhances biodiversity

  4. All of the above


Correct Option: D
Explanation:

Forest restoration involves the reestablishment of forest cover on degraded or deforested land, leading to increased carbon sequestration, reduced greenhouse gas emissions, and enhanced biodiversity.

What is the term used to describe the process of replacing fossil fuels with renewable energy sources?

  1. Decarbonization

  2. Electrification

  3. Energy transition

  4. Carbon capture and storage


Correct Option: A
Explanation:

Decarbonization refers to the process of reducing or eliminating the use of fossil fuels and transitioning to renewable energy sources, thereby reducing greenhouse gas emissions.

How does the conservation of existing forests contribute to climate change mitigation?

  1. It prevents deforestation

  2. It maintains carbon sinks

  3. It reduces greenhouse gas emissions

  4. All of the above


Correct Option: D
Explanation:

Conserving existing forests prevents deforestation, maintains carbon sinks, and reduces greenhouse gas emissions, all of which contribute to climate change mitigation.
