Greenhouse Gases | MCQs

Explanation

Oxygen (O2) is not a greenhouse gas.

Greenhouse gases are gases in the Earth's atmosphere that absorb and emit radiation, trapping heat and contributing to the Greenhouse Effect.

The main greenhouse gases are:

• Carbon dioxide (CO2)
• Methane (CH4)
• Nitrous oxide (N2O)
• Water vapor (H2O)
• Ozone (O3)
• Chlorofluorocarbons (CFCs)
• Hydrofluorocarbons (HFCs)
• Perfluorocarbons (PFCs)

Explanation

• Carbon dioxide (CO2) is produced when trees and fossil fuels are burned, through a process called combustion.
• Combustion releases carbon dioxide and water vapor into the atmosphere.

Explanation

• Carbon dioxide (CO2) is a greenhouse gas that plays a significant role in the Earth's greenhouse effect.
• It traps heat radiated from the Earth's surface, maintaining the Earth's temperature and keeping it warm enough to support life.
• Other greenhouse gases include methane (CH4), water vapor (H2O), and nitrous oxide (N2O).
