  1. Carbon dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous oxide (N2O)

  4. Water vapor (H2O)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbon dioxide (CO2) is the primary greenhouse gas emitted by human activities that contributes to climate change. It is released into the atmosphere through the burning of fossil fuels, deforestation, and other human activities.

Multiple choice

Which sector is responsible for the largest share of global CO2 emissions?

  1. Transportation

  2. Electricity generation

  3. Industry

  4. Agriculture
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Electricity generation, particularly from fossil fuel-based power plants, is the largest contributor to global CO2 emissions.

Multiple choice

Which technology is used to capture CO2 directly from the air?

  1. Direct air capture (DAC)

  2. Post-combustion capture

  3. Pre-combustion capture

  4. Oxyfuel combustion
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Direct air capture (DAC) is a technology that aims to capture CO2 directly from the ambient air, rather than from specific industrial sources.

Multiple choice

How does mining contribute to greenhouse gas emissions?

  1. Through the use of heavy machinery and equipment during mining operations.

  2. By releasing methane and carbon dioxide during coal mining activities.

  3. As a result of deforestation and habitat destruction associated with mining.

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mining activities contribute to greenhouse gas emissions through various means, including the use of fossil fuels for machinery and equipment, the release of methane and carbon dioxide during coal mining, and deforestation and habitat destruction associated with mining operations.

  2. Methane (CH4)

  3. Nitrogen (N2)

  4. Nitrous Oxide (N2O)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Nitrogen (N2) is not a primary greenhouse gas, while Carbon Dioxide (CO2), Methane (CH4), and Nitrous Oxide (N2O) are.

Multiple choice

What is the primary greenhouse gas emitted by transportation activities?

  1. Carbon dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous oxide (N2O)

  4. Hydrofluorocarbons (HFCs)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbon dioxide (CO2) is the primary greenhouse gas emitted by transportation activities, accounting for over 70% of total transportation-related emissions. CO2 is produced when fossil fuels, such as gasoline and diesel, are burned for transportation purposes.

Multiple choice

Which of the following is NOT a greenhouse gas emitted by transportation activities?

  1. Carbon dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous oxide (N2O)

  4. Oxygen (O2)
