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

Estimates suggest that the global capacity for carbon storage in geological formations is in the range of 10,000 gigatons of CO2, providing significant potential for long-term storage of captured carbon.

Multiple choice

Which sector is responsible for the majority of CO2 emissions that can be captured and stored through CCS?

  1. Transportation

  2. Residential and commercial buildings

  3. Industrial processes

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

Industrial processes, such as cement production, steel manufacturing, and chemical processing, are responsible for a significant portion of CO2 emissions that can be captured and stored through CCS.

Multiple choice

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

  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, while carbon dioxide, methane, and nitrous oxide are.

Multiple choice

Which technology involves the direct capture of CO2 from the ambient air?

  1. Direct air capture (DAC)

  2. Carbon capture and utilization (CCU)

  3. Enhanced oil recovery (EOR)

  4. Chemical looping combustion (CLC)
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Direct air capture (DAC) technologies aim to remove CO2 directly from the ambient air using various methods, such as chemical absorption, adsorption, or membrane separation.

Multiple choice

What is the primary greenhouse gas emitted by human activities?

  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 emitted by human activities, primarily through the burning of fossil fuels.

Multiple choice

Which metric assesses the potential contribution of a chemical substance to global warming?

  1. Global Warming Potential

  2. Ozone Depletion Potential

  3. Photochemical Ozone Creation Potential

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

Global Warming Potential quantifies the heat-trapping ability of a greenhouse gas relative to carbon dioxide, providing insights into its contribution to climate change.

Multiple choice

What is the primary source of greenhouse gas emissions from rice cultivation?

  1. Methane

  2. Carbon dioxide

  3. Nitrous oxide

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

The primary source of greenhouse gas emissions from rice cultivation is methane. Methane is a potent greenhouse gas that is released from rice paddies when organic matter decomposes in flooded conditions. Methane emissions from rice cultivation can be reduced by using alternate wetting and drying irrigation techniques, which involve flooding and draining rice paddies periodically.

Multiple choice

Which sector in India contributes the most to greenhouse gas emissions?

  1. Agriculture

  2. Industry

  3. Transportation

  4. Residential and commercial buildings
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The industrial sector in India is the largest contributor to greenhouse gas emissions, accounting for approximately 35% of the total emissions. This is primarily due to the use of fossil fuels for energy generation and industrial processes.

Multiple choice

Which of the following is NOT a greenhouse gas?

  1. Carbon dioxide

  2. Methane

  3. Oxygen

  4. Water vapor
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Oxygen is not a greenhouse gas because it does not absorb and trap heat in the atmosphere like carbon dioxide, methane, and water vapor do.

Multiple choice

Which of the following is not a greenhouse gas?

  1. Carbon dioxide

  2. Methane

  3. Oxygen

  4. Water vapor
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Greenhouse gases are gases that trap heat in the Earth's atmosphere. Carbon dioxide, methane, and water vapor are all greenhouse gases, while oxygen is not.
