Help 10 points!! What is the "greenhouse" effect?

Answer 1

Greenhouse gases, like CO2 and water vapor, trap the sun's heat in the atmosphere, like a greenhouse. This causes global temperatures to rise. CO2 is mainly given off from burning fossil fuels for energy. The recent rise in CO2 is considered partly responsible for the recent rise in average temperatures. This trapping of the sun's heat is referred to as the greenhouse effect and the rise in temperature is often called climate change or global warming.

Answer 2

The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60ºF colder. Because of how they warm our world, these gases are referred to as greenhouse gases
