Understanding Climate Change and the Carbon Cycle

What are the three main pools where Earth's carbon is stored?

• Plants, animals, and rocks

• Forests, rivers, and soil

• Land, the oceans, and the atmosphere

• Mountains, lakes, and underground

How does burning fossil fuels affect the carbon cycle?

• It enhances plant growth globally

• It decreases the amount of carbon in the atmosphere

• It has no significant impact on the carbon cycle

• It moves carbon from underground to the atmosphere

How do thawing frozen soils contribute to climate change?

• By increasing the Earth's albedo

• By activating microorganisms that release carbon

• By absorbing more sunlight

• By releasing trapped gases that cool the atmosphere

What is a positive feedback loop in the context of climate change?

• A process that decreases global temperatures

• A beneficial cycle that reduces carbon in the atmosphere

• A vicious cycle that increases warming

• A cycle that helps plants grow faster

Why aren't negative feedback loops enough to solve climate change?

• They only work in cold environments

• They reduce biodiversity

• They increase the temperature further

• They can't absorb enough carbon
