Science Review

1. Gases in the air, what are they?  Nitrogen, oxygen and other gases such as carbon dioxide.


2. Why are these gases beneficial? Plants need nitrogen and we need oxygen to survive. Trees absorb carbon dioxide and give off oxygen.

3. What is air pressure? It is the weight of air as it is pressed down.


4. What are the four layers of the atmosphere? Troposhere, stratosphere,mesosphere and thermosphere

5. Which is the most important layer for human life? Troposphere

6. What is the grrenhouse effect?

Earth's atmosphere does the same thing as the greenhouse. Gases in the atmosphere such as carbon dioxide do what the roof of a greenhouse does. During the day, the Sun shines through the atmosphere. Earth's surface warms up in the sunlight. At night, Earth's surface cools, releasing the heat back into the air. But some of the heat is trapped by the greenhouse gases in the atmosphere. That's what keeps our Earth a warm and cozy 59 degrees Fahrenheit, on average.

Greenhouse effect of Earth's atmosphere keeps some of the Sun's energy from escaping back into space at night.

The point is, if the greenhouse effect is too strong, Earth gets warmer and warmer. This is what is happening now. Too much carbon dioxide and other greenhouse gases in the air are making the greenhouse effect stronger.

Every place has its own climate, whether Arctic cold, tropical warm, or something in between. Averaging them all together makes global climate.
