  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. It is released into the atmosphere through human activities such as burning fossil fuels and deforestation.

Multiple choice

Which of the following is a major source of methane (CH4) emissions, contributing to climate change?

  1. Deforestation

  2. Industrial Processes

  3. Transportation

  4. Livestock Production
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Livestock Production, particularly the raising of cattle and other ruminants, is a major source of methane emissions due to the digestive processes of these animals.

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.
