Explain how burning fossil fuels contributes to global warming.

Burning fossil fuels releases carbon dioxide into the atmosphere, which is a greenhouse gas that traps heat in Earth's lower atmosphere and causes global warming. Signup and view all the answers

What is the relationship between greenhouse gases and the heat absorbed by the Earth's lower atmosphere?

Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Signup and view all the answers

Greenhouse effect

The process where certain gases in the atmosphere trap heat from the sun, warming the Earth's surface.

Greenhouse gases

Gases that contribute to the greenhouse effect by trapping heat in the atmosphere. Examples include carbon dioxide, methane, and nitrous oxide.

Fossil fuels

Energy sources formed over millions of years from decayed organic matter, like coal, oil, and natural gas.
