The greenhouse effect is when the temperature rises because the sun's heat and
Light is trapped in the earth's atmosphere. This is like when heat is trapped in car. On a very hot day,the car gets hotter when it is out in the parking lot. This is becuase the heat and light from the sun car get into the car, by going through the windows , but it can't get back out. This is what 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. Sometimes the temperature can change in a way the helps us. The greenhouse effect makes the earth approprate for people to live on. Without it, the earth would be freezing, or on the other hand it would be burning hot. It would be freezing at night because the sun would be down. We would not get the sun's heat and light to make the right somewhat warm. During the day, especially during the summer, it would be burning because the sun would be up with no asmosphere to filter it, so people, plants, and animsls would be exposed to all the light and heat. Although the greenhouse effect makes the earth able to have people livng on it , if there gets to be too many gases, the earth can get unusually warmmer, and many plants, animals, and people will die. They would die because the plants would not be able to take the heat. This would case us to have less food to eat , but it would also limit the food that animals have. With less food, gradually, people, plants, and animals would all die of hunger.
