What is the primary greenhouse gas emitted by human activities?

  1. Carbon Dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous Oxide (N2O)

  4. Sulfur Hexafluoride (SF6)


Correct Option: A
Explanation:

Carbon Dioxide (CO2) is the primary greenhouse gas emitted by human activities, primarily from the burning of fossil fuels.

Which sector contributes the largest share of global carbon dioxide emissions?

  1. Transportation

  2. Electricity Generation

  3. Industry

  4. Agriculture


Correct Option: B
Explanation:

Electricity generation, particularly from fossil fuel-based power plants, is the largest contributor to global carbon dioxide emissions.

How do carbon emissions contribute to the greenhouse effect?

  1. They trap heat in the atmosphere.

  2. They cause ozone depletion.

  3. They increase solar radiation.

  4. They reduce cloud cover.


Correct Option: A
Explanation:

Carbon emissions contribute to the greenhouse effect by trapping heat in the atmosphere, leading to an increase in global temperatures.

What is the term used to describe the long-term increase in Earth's average surface temperature?

  1. Global Warming

  2. Climate Change

  3. Greenhouse Effect

  4. Carbon Footprint


Correct Option: A
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 NOT a direct result of increased carbon emissions?

  1. Rising Sea Levels

  2. More Frequent and Intense Heatwaves

  3. Increased Precipitation

  4. Ocean Acidification


Correct Option: C
Explanation:

While carbon emissions contribute to climate change, increased precipitation is not a direct result of increased carbon emissions alone.

How does ocean acidification impact marine ecosystems?

  1. It harms coral reefs.

  2. It affects the growth of phytoplankton.

  3. It disrupts the food chain.

  4. All of the above


Correct Option: D
Explanation:

Ocean acidification caused by increased carbon emissions harms coral reefs, affects the growth of phytoplankton, and disrupts the marine food chain.

What is the term used to describe the amount of greenhouse gases produced to directly and indirectly support human activities?

  1. Carbon Footprint

  2. Ecological Footprint

  3. Water Footprint

  4. Energy Footprint


Correct Option: A
Explanation:

Carbon Footprint refers to the amount of greenhouse gases produced to directly and indirectly support human activities.

Which of the following is NOT a renewable energy source?

  1. Solar Energy

  2. Wind Energy

  3. Hydropower

  4. Natural Gas


Correct Option: D
Explanation:

Natural Gas is a fossil fuel and not a renewable energy source.

What is the primary goal of the Paris Agreement?

  1. To limit global temperature rise to well below 2 degrees Celsius.

  2. To phase out fossil fuels by 2050.

  3. To promote sustainable development.

  4. To enhance climate resilience.


Correct Option: A
Explanation:

The primary goal of the Paris Agreement is to limit global temperature rise to well below 2 degrees Celsius, preferably to 1.5 degrees Celsius, compared to pre-industrial levels.

Which of the following is NOT a strategy for reducing carbon emissions?

  1. Promoting energy efficiency

  2. Investing in renewable energy

  3. Planting trees

  4. Increasing the use of fossil fuels


Correct Option: D
Explanation:

Increasing the use of fossil fuels would result in higher carbon emissions, not lower.

What is the term used to describe the process of removing carbon dioxide from the atmosphere?

  1. Carbon Capture and Storage (CCS)

  2. Carbon Capture and Utilization (CCU)

  3. Carbon Sequestration

  4. Carbon Offsetting


Correct Option: A
Explanation:

Carbon Capture and Storage (CCS) refers to the process of capturing carbon dioxide from industrial sources and storing it underground or in geological formations.

Which of the following is NOT a consequence of climate change?

  1. More frequent and intense storms

  2. Melting glaciers and ice caps

  3. Increased agricultural productivity

  4. Rising sea levels


Correct Option: C
Explanation:

While climate change can have both positive and negative impacts on agriculture, increased agricultural productivity is not a universal consequence.

What is the term used to describe the ability of an ecosystem to absorb and store carbon dioxide?

  1. Carbon Sink

  2. Carbon Source

  3. Carbon Footprint

  4. Carbon Cycle


Correct Option: A
Explanation:

Carbon Sink refers to an ecosystem or process that absorbs and stores more carbon dioxide than it releases.

Which of the following is NOT a greenhouse gas?

  1. Carbon Dioxide (CO2)

  2. Methane (CH4)

  3. Water Vapor (H2O)

  4. Nitrous Oxide (N2O)


Correct Option: C
Explanation:

Water Vapor is not a greenhouse gas in the context of human-induced climate change.

How does deforestation contribute to carbon emissions?

  1. It releases stored carbon into the atmosphere.

  2. It reduces the Earth's albedo.

  3. It disrupts the water cycle.

  4. All of the above


Correct Option: D
Explanation:

Deforestation contributes to carbon emissions by releasing stored carbon into the atmosphere, reducing the Earth's albedo, and disrupting the water cycle.
