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

Carbon Dioxide (CO2) is the primary greenhouse gas responsible for human-induced climate change, contributing significantly to the greenhouse effect.

Multiple choice

What is the role of permafrost in the global carbon cycle?

  1. Permafrost acts as a carbon sink.

  2. Permafrost acts as a carbon source.

  3. Permafrost has no role in the global carbon cycle.

  4. Permafrost acts as both a carbon sink and a carbon source.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Permafrost acts as both a carbon sink and a carbon source. It stores carbon in the form of organic matter, but it can also release carbon into the atmosphere when it thaws.
