The greenhouse effect helps keep the Earth warm by trapping heat from the sun. Without the greenhouse effect, Earth would be too cold for humans, animals, and plants to survive. But too much of it can make the planet too hot, leading to problems like climate change.Process of Greenhouse EffectThe sun sends light and heat to Earth.Some of this heat bounces back into space, but some get trapped by gases in the atmosphere, like carbon dioxide and water vapor.These gases act like a blanket, keeping enough heat to make Earth warm and livable.
