What are four ways that the atmosphere is like a security blanket for life on Earth?
1. It absorbs harmful radiation from the sun.
2. It burns up meteors before they hit the Earth.
3. It lets just enough of the sun's rays through to warm the Earth during the day without frying us.
4. At night, it holds in enough heat from the sun during the day to keep us from freezing
What are the five layers of the Earth's atmosphere?
Troposphere, stratosphere, mesosphere, thermosphere, and the exosphere
With about of ton of air pushing against us all the time, why aren't we crushed?
... because the pressure inside our bodies equals the pressure pushing on us from the atmosphere.
Why does weather only happen in the Troposphere layer of the atmosphere?
...because it's the only layer that has enough water vapor to form clouds or fog.
Why do cold air molecules weigh more and put more pressure on the Earth?
... because cold air molecules are _______ ________ _________.
... packed closer together (than air hotter air molecules).
