Front

Why is burning fossil fuels harmful?

Back

Burning fossil fuels is harmful because it increases the amount of carbon dioxide in the atmosphere.

Front

Which process does NOT move carbon to the atmosphere?

Back

Photosynthesis does not move carbon to the atmosphere.

Front

What is the atmosphere?

Back

The atmosphere is the layer of gases surrounding Earth, which contains carbon dioxide and is involved in the carbon cycle.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce atmospheric carbon levels.

Front

What is the lithosphere?

Back

The lithosphere is the solid outer part of the Earth, including rocks and soil, which stores carbon in fossil fuels and minerals.

Front

How does animal respiration contribute to the carbon cycle?

Back

Animal respiration releases carbon dioxide into the atmosphere as animals breathe.

Front

What is carbon sequestration?

Back

Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide to mitigate climate change.
