    Explain how burning fossil fuels contributes to global warming.

    <p>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.</p> Signup and view all the answers

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

    <p>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.</p> Signup and view all the answers
