Unformatted text preview: Everyday Science Global Warming Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die. Greenhouse effect The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. The heat and light can get through the atmosphere, but it can’t get out. As a result, the temperature rises. The greenhouse effect makes the earth appropriate 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 night somewhat warm. During the day, especially during the summer, it would be burning because the sun If there gets to be too many gases, the earth can get unusually warmer, and many plants, animals, and people will die because there would be less food (plants like corn, wheat, and other vegetables and fruits)....
