Atmosphere - Nicholas Leduc
#1. The Atmosphere is made up of four layers. The Troposphere, Stratosphere, Mesosphere, and the Thermosphere.
#2. In the middle of the Stratosphere there is a part called the Ozone layer. The Ozone layer protects us from the suns dangerous ultraviolet rays.
#3. As you go higher in the atmosphere the changes. As you go, the Troposphere gets really cold. The Stratosphere gets warmer as you go higher. The Mesosphere gets cold as you go, and the Troposphere is the hottest of them all.
#4. Higher in the atmosphere there is less pressure. Down on the surface there is less space for the air molecules to be in so there is pressure because there is so much air. Higher in the Atmosphere there is less air because there is more space. There is less pressure because there is not a lot of air. As you go higher pressure decreases.
#5. The most common gases in the air are nitrogen and oxygen. Nitrogen makes up approximately 79% of our air and Oxygen makes up approximately 20% of our air. All of the other gases in our air only make 1% of it. You do breathe in the nitrogen you just breathe right back out.
#6. There is something that happens that is called the green house effect. This is what happens when the light comes through the atmosphere and gives of energy in the form of heat. It bounces of the Earth and back towards space. Because there is Carbon Dioxide in the air it traps the heat in. It keeps us warm.
#7. That thin layer of blue around the Earth is the Atmosphere. Even though the Atmosphere is about 320 Km tall It is very thin compared to the Earth. Even though it is so small it is the reason we are alive.
#8. There has been a rise in Carbon Dioxide in the past few years. You can help by not using a lot of things that produce Carbon Dioxide.
