What is the greenhouse effect?
The greenhouse effect is when temperature rises because the sun's heat and light is trapped in the heart's atmosphere. This is like when heat is helped in a car. On a very hot day,the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can gat into the car,by going through the Windows,but it can't get back out. This is what the greenhouse effect does to the earth. The heat and light can get through the atmosphere,but it can't get out. As a result,the temperature rises.
