Animals release this compound when they breathe out.
carbon dioxide
What are the two largest reservoirs for carbon dioxide?

When humans burn fossil fuels, most of the carbon quickly enters the_____________ as carbon dioxide.
atmosphere
Name one way humans increase the carbon levels on earth.
burning fossil fuels, deforestation/urbanization, farming...
The process through which plants take in carbon dioxide from the atmosphere.
Photosynthesis
How does deforestation contribute to an increase in carbon in the atmosphere?
By removing trees - trees take carbon out of the atmosphere during photosynthesis. Less plants, more carbon in the atmosphere.
How do plants affect the air that animals and people breathe?
Plants take in carbon dioxide and release oxygen
Explain how volcanic eruptions cause climate change.
Volcanic eruptions cause climate change by releasing ash and gasses into the atmosphere blocking the sun and cooling the earth's temperature for a short time.
True/False: All of the carbon in existence is continually recycled in the carbon cycle.
True
How does carbon dioxide contribute to the greenhouse effect?
Too much carbon dioxide in the atmosphere heats up the Earth.
