Carbon Cycle and Climate Change

Why is the Carbon Cycle important?

• To understand carbon storage and climate

• To produce more energy for ourselves

• To create industrial products that we can sell

• To dispose of waste materials more quickly

Select all statements that are true.

• Burning fossil fuels extracted from the ground increases CO2, in the atmosphere and cools the planet.

• Burning fossil fuels extracted from the ground increases CO2 and warms the planet, by thickening the greenhouse effect.

• Examples of fossil fuels are: coal,

  natural gas,

  petroleum,

• The ocean absorbs CO2, and makes the ocean more acidic, which benefits the oceans' ecosystems.
