  1. Transportation

  2. Industry

  3. Residential

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

The industrial sector is responsible for the largest share of greenhouse gas emissions globally. This includes emissions from manufacturing, mining, and construction activities.

Multiple choice

Which of the following is NOT a greenhouse gas?

  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. Greenhouse gases are gases that trap heat in the atmosphere, causing the planet to warm. Carbon dioxide, methane, and nitrous oxide are all greenhouse gases.

Multiple choice

Which country is the largest emitter of greenhouse gases?

  1. China

  2. United States

  3. India

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

China is the largest emitter of greenhouse gases, followed by the United States, India, and Russia.

Multiple choice

Which of the following industries is a major contributor to CO2 emissions and a potential target for CCS implementation?

  1. Power generation

  2. Transportation

  3. Agriculture

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

Power generation, particularly from fossil fuel-based plants, is a major contributor to CO2 emissions. CCS can be applied to capture CO2 from power plants and prevent its release into the atmosphere.

Multiple choice

What is the primary component of the Earth's atmosphere?

  1. Oxygen

  2. Nitrogen

  3. Carbon Dioxide

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

Nitrogen makes up approximately 78% of the Earth's atmosphere, followed by Oxygen at 21%.

Multiple choice

Which greenhouse gas is primarily responsible for the enhanced greenhouse effect and global warming?

  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 contributing to the enhanced greenhouse effect and global warming.

Multiple choice

What is the primary greenhouse gas emitted by human activities that contributes to 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 (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
