Write short note on 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 earths atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die.
What is the greenhouse effect?
The greenhouse effect is when the temperature rises because the suns heat and light is trapped in the earths atmosphere. This is like when heat is trapped 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 get into the car, by going through the windows, but it cant get back out. This is what the greenhouse effect does to the earth. The heat and light can get through the atmosphere, but it cant get out. As a result, the temperature rises.
