Carbon is a greenhouse gas. How are greenhouse gases beneficial (good) for the Earth?
Keeps Earth at a livable temperature
Protects the Earth from ultraviolet radiation
Burns up meteors that enter the atmosphere
How does deforestation affect the carbon cycle?
It releases a large amount of stored carbon
