Which of the following is a major source of air pollution?

  1. Renewable energy sources

  2. Industrial activities

  3. Electric vehicles

  4. Natural vegetation


Correct Option: B
Explanation:

Industrial activities, such as manufacturing and power generation, release various pollutants into the air, including particulate matter, sulfur dioxide, and nitrogen oxides.

What is the primary greenhouse gas responsible for human-induced climate change?

  1. Oxygen

  2. Carbon dioxide

  3. Nitrogen

  4. Argon


Correct Option: B
Explanation:

Carbon dioxide is the primary greenhouse gas contributing to human-induced climate change. It traps heat in the atmosphere, leading to an increase in global temperatures.

How does air pollution affect human health?

  1. Improved respiratory function

  2. Increased risk of cardiovascular diseases

  3. Enhanced immune system

  4. Reduced risk of cancer


Correct Option: B
Explanation:

Air pollution can contribute to an increased risk of cardiovascular diseases, such as heart attacks and strokes, due to the harmful effects of pollutants on the heart and blood vessels.

Which of the following is a potential impact of climate change on ecosystems?

  1. Increased biodiversity

  2. Enhanced soil fertility

  3. Reduced risk of wildfires

  4. Shifts in species distribution and abundance


Correct Option: D
Explanation:

Climate change can lead to shifts in species distribution and abundance, as species adapt or migrate to suitable habitats with changing environmental conditions.

What is the term used to describe the gradual increase in the Earth's average temperature?

  1. Global cooling

  2. Global warming

  3. Temperature fluctuation

  4. Climate stability


Correct Option: B
Explanation:

Global warming refers to the long-term increase in Earth's average surface temperature, primarily due to the accumulation of greenhouse gases in the atmosphere.

Which of the following is a renewable energy source that does not contribute to air pollution?

  1. Coal-fired power plants

  2. Solar photovoltaic systems

  3. Natural gas-powered vehicles

  4. Wind turbines


Correct Option: B
Explanation:

Solar photovoltaic systems generate electricity from sunlight without emitting air pollutants, making them a clean and renewable energy source.

What is the primary source of methane, a potent greenhouse gas?

  1. Deforestation

  2. Volcanic eruptions

  3. Industrial processes

  4. Livestock farming


Correct Option: D
Explanation:

Livestock farming, particularly the digestive processes of ruminant animals, is a significant source of methane emissions, contributing to the increase in greenhouse gas concentrations.

What is the role of forests in mitigating climate change?

  1. Releasing greenhouse gases into the atmosphere

  2. Increasing the Earth's albedo

  3. Absorbing carbon dioxide through photosynthesis

  4. Reducing the amount of solar radiation reaching the Earth


Correct Option: C
Explanation:

Forests play a crucial role in mitigating climate change by absorbing carbon dioxide through photosynthesis, effectively removing it from the atmosphere and storing it in biomass and soil.

Which of the following is a potential consequence of rising sea levels due to climate change?

  1. Increased coastal erosion

  2. Enhanced agricultural productivity

  3. Reduced risk of flooding

  4. Improved water quality


Correct Option: A
Explanation:

Rising sea levels can lead to increased coastal erosion, threatening coastal communities and infrastructure, and displacing ecosystems.

What is the term used to describe the process of reducing greenhouse gas emissions to mitigate climate change?

  1. Carbon capture and storage

  2. Climate adaptation

  3. Greenhouse gas sequestration

  4. Mitigation


Correct Option: D
Explanation:

Mitigation refers to the efforts taken to reduce greenhouse gas emissions and limit the effects of climate change, typically involving the transition to renewable energy sources, energy efficiency measures, and sustainable land use practices.

Which of the following is a potential impact of climate change on agricultural productivity?

  1. Increased crop yields due to higher temperatures

  2. Reduced risk of pests and diseases

  3. Improved soil moisture content

  4. Shifts in growing seasons and crop suitability


Correct Option: D
Explanation:

Climate change can lead to shifts in growing seasons and changes in temperature and precipitation patterns, affecting the suitability of certain crops in specific regions.

What is the primary source of black carbon, a major component of air pollution?

  1. Natural gas combustion

  2. Biomass burning

  3. Solar radiation

  4. Electric vehicles


Correct Option: B
Explanation:

Biomass burning, including forest fires and agricultural burning, is a significant source of black carbon, a type of particulate matter that contributes to air pollution and climate change.

Which of the following is a potential consequence of increased air pollution on ecosystems?

  1. Enhanced biodiversity

  2. Improved soil fertility

  3. Reduced risk of wildfires

  4. Disruption of ecological balance


Correct Option: D
Explanation:

Increased air pollution can disrupt the ecological balance by affecting plant and animal life, altering food chains, and reducing biodiversity.

What is the term used to describe the process of capturing and storing carbon dioxide from the atmosphere to mitigate climate change?

  1. Carbon capture and storage

  2. Climate adaptation

  3. Greenhouse gas sequestration

  4. Mitigation


Correct Option: A
Explanation:

Carbon capture and storage (CCS) involves capturing carbon dioxide from industrial sources or the atmosphere and storing it underground or in geological formations to reduce its impact on climate change.
