Earth's atmosphere is a collection of gases and particles in the sky.
2. Why is earth's atmosphere not considered pure air?
Earth's atmosphere is not considered pure air because there are particles in the atmosphere such as dust.
3. What is the composition of earth's atmosphere?
Nitrogen accounts for 78%.
Oxygen accounts for 21%
Other accounts for 1%
4. What gas makes up most of earth's atmosphere?
Nitrogen makes up 78% of the Earth's atmosphere which is the most of all the others.
5. Explain why earth's atmosphere is important.
Without Earth's atmosphere the water cycle could not work. Also, the temperature would be unstable, causing uncontrollable weather. Protects us from UV Sun Rays. Has essential gases to life.]]> 2017-01-11 17:39:11 UTC https://padlet.com/loppma/etbm2do145jk/wish/146589514 loppma https://padlet.com/loppma/etbm2do145jk/wish/148170241 1. Why does air have pressure and density?
Air has pressure and density because air has mass and mass has gravity.
2. What is air pressure?
The force of the weight of column of air
3. What is density?
The amount of mass in a given volume.
4. How does air pressure and density change with altitude?
Air pressure and density decrease when altitude increases.
5. Why does air pressure change with altitude?
At higher elevation the air molecules spread out and decrease.]]> 2017-01-19 17:37:16 UTC https://padlet.com/loppma/etbm2do145jk/wish/148170241 loppma https://padlet.com/loppma/etbm2do145jk/wish/148800225 1. What divides earth's atmosphere into different layers?
Temperature divides Earth's atmosphere into different layers.
2. Identify the layers the atmosphere from earth's surface to space.
Troposphere, Stratosphere, Mesosphere, Thermosphere
3. Which layer of earth's atmosphere contains ozone and what does ozone do?
Stratosphere. Blocks us from UV rays
4. What is the hottest layer of earth's atmosphere? How hot is it?
Thermosphere 18000 C
5. What layer contains earth's weather?
Troposphere 
6. What layer protects earth's surface from meteors?
Mesosphere.]]> 2017-01-23 17:41:14 UTC https://padlet.com/loppma/etbm2do145jk/wish/148800225 loppma https://padlet.com/loppma/etbm2do145jk/wish/149400326 1. What is the source of all energy on earth? The Sun
2. How does that energy reach earth through space? Radiation
3. What happens to that energy after it reaches earth's atmosphere?It slowly depletes through the layers of the atmosphere.
4. How much of the 100% of energy that reaches the troposphere actually makes it to earth's surface? Why? 50% of the rays reach the surface of Earth.
5. What process traps heat on earth's surface? Why is this important? Greenhouse Effect is the trapping of heat and energy through the atmosphere. ]]> 2017-01-25 17:36:40 UTC https://padlet.com/loppma/etbm2do145jk/wish/149400326 loppma https://padlet.com/loppma/etbm2do145jk/wish/149938797 1. Compare and contrast temperature and thermal energy.
2. What happens to the motion of particles as the temperature of a substance increases?
3. What is heat?
4. Describe the three ways that heat is transferred?]]> 2017-01-27 17:09:38 UTC https://padlet.com/loppma/etbm2do145jk/wish/149938797
