Question

Quizplus · Accepted Answer

The normal process that warms the Earth's surface and lower atmosphere is the greenhouse effect. This occurs when certain gases, such as carbon dioxide and methane, trap heat from the sun in the atmosphere and prevent it from escaping into space. This is a natural process that has been occurring for millions of years, but human activities, such as burning fossil fuels, have increased the levels of these greenhouse gases in the atmosphere, causing the Earth's temperature to rise.
