Multiple choice

What is the impact of human activities on the composition of the Earth's atmosphere?

  1. Human activities have increased the concentration of greenhouse gases in the atmosphere

  2. Human activities have decreased the concentration of greenhouse gases in the atmosphere

  3. Human activities have had no impact on the concentration of greenhouse gases in the atmosphere

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Human activities, such as the burning of fossil fuels, have increased the concentration of greenhouse gases in the atmosphere, leading to global warming and climate change.

Multiple choice

Which of the following is NOT a greenhouse gas?

  1. Carbon dioxide (CO2)

  2. Methane (CH4)

  3. Water vapor (H2O)

  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 Earth's temperature to rise. Water vapor is a greenhouse gas, but it is a natural component of the atmosphere and does not contribute to climate change in the same way that human-produced greenhouse gases do.
