Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Fossil fuel extraction and combustion, such as the burning of coal, oil, and natural gas for energy production, transportation, and industrial processes, are significant sources of greenhouse gases, contributing to climate change.

Multiple choice

Which of the following is NOT a greenhouse gas?

  1. Carbon Dioxide (CO2)

  2. Methane (CH4)

  3. Nitrogen (N2)

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

Nitrogen is not a greenhouse gas because it does not absorb and trap heat in the atmosphere like other greenhouse gases such as CO2, CH4, and H2O.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mangrove deforestation contributes to greenhouse gas emissions by releasing carbon dioxide, methane, and nitrous oxide, all of which contribute to global warming.

Multiple choice

How can composting help reduce greenhouse gas emissions?

  1. By diverting organic waste from landfills

  2. By reducing the need for chemical fertilizers

  3. By capturing carbon dioxide from the atmosphere

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

Composting helps reduce greenhouse gas emissions by diverting organic waste from landfills, reducing the need for chemical fertilizers, and capturing carbon dioxide from the atmosphere.

Multiple choice

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

  1. Carbon dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous oxide (N2O)

  4. Oxygen (O2)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Oxygen is not a greenhouse gas, as it does not trap heat in the atmosphere like other greenhouse gases.

Multiple choice

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

  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 is the primary greenhouse gas responsible for human-caused climate change. It is released into the atmosphere through human activities such as burning fossil fuels, deforestation, and cement production.

Multiple choice

Which of the following is a greenhouse gas?

  1. Carbon dioxide (CO2)

  2. Methane (CH4)

  3. Nitrous oxide (N2O)

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

Carbon dioxide, methane, and nitrous oxide are all greenhouse gases. They trap heat in the Earth's atmosphere, causing the planet to warm.

Multiple choice

What is the primary greenhouse gas emitted by forest fires?

  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

Forest fires release large amounts of carbon dioxide into the atmosphere, contributing to the greenhouse effect and global warming.

Multiple choice

How do wetlands contribute to the global carbon cycle?

  1. Wetlands act as carbon sinks, absorbing and storing carbon dioxide from the atmosphere.

  2. Wetlands release carbon dioxide into the atmosphere, contributing to greenhouse gas emissions.

  3. Wetlands have no significant impact on the global carbon cycle.

  4. Wetlands convert carbon dioxide into oxygen through photosynthesis.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Wetlands play a crucial role in the global carbon cycle by acting as carbon sinks. They absorb and store carbon dioxide from the atmosphere through the process of photosynthesis, helping to regulate greenhouse gas levels and mitigate climate change.

Multiple choice
