Density
What does Density tell us?
Tells us how tightly packed something is
What is atmospheric pressure?
is the force exerted by the weight of air above a given point
What is the first layer of the atmosphere?
Troposhere
What is the greenhouse effect?
Process that occurs when gases in Earth’s atmosphere trap the sun’s heat being reflected back from the surface.
What two factors change density?
Altitude and Temperature
What percentage of the atmosphere is made up of Oxygen?
21%
Just like density what two factors change atmospheric pressure?
Altitude and temperature
What is the last layer of the atmosphere
Exosphere
How does the greenhouse effect help us?
helps keep the earth at a regulated temperature helping support life on earth
What does Altitude tell us?
How high or low something is (from sea level)
What percentage of the atmosphere is Nitrogen?
78%
What do we measure atmospheric pressure with?
Barometer
Which layer of the atmosphere holds the ozone layer?
Stratosphere
Burning fossil fuels, gas, oil
The higher you go in altitude what happens to the density of the air?
decreases
What percentage of the atmosphere is made up of Carbon Dioxide?
Less than 1%
Why do mountain climbers wear safety gear when climbing to higher altitudes (EXPLAIN)?
Because the air is thinner, it is harder to breathe due to the low density of the air
Global Warming
When we say something has "High Density" what do we mean?
The air is tightly packed; there are more air molecules in the air
A colorless gas produced by burning fossil fuels, oil and gas
Decrease
What layer is responsible for burning up meteors?
Mesosphere
What environmental disasters happen if the planet warms too much?
