Carbon Cycle

Front

What is the lithosphere in the context of the carbon cycle?

Back

The lithosphere is the reservoir of carbon made up of the ground, including soil, rocks, fossil fuels, and other geological formations.

How does the carbon cycle compare to the water cycle?

Back

Both the carbon cycle and the water cycle involve the transfer of substances between animals, plants, and the Earth.

Front

What impact does deforestation have on global warming?

Back

Deforestation increases global warming because trees absorb carbon dioxide, and removing them allows more carbon to remain in the atmosphere.

What is one way carbon can move between different spheres of the Earth?

Back

Carbon can move from the lithosphere to the hydrosphere through processes like weathering and erosion.

Explain the term 'carbon sink.'

Back

A carbon sink is a natural reservoir that stores carbon-containing chemical compounds for an indefinite period, such as forests and oceans.

What is the significance of fossil fuels in the carbon cycle?

Back

Fossil fuels are a major source of carbon emissions when burned, contributing to the increase of carbon dioxide in the atmosphere.

How does weathering contribute to the carbon cycle?

Back

Weathering breaks down rocks, releasing carbon into the soil and water, facilitating its movement through the carbon cycle.
