100
a layer of gases that surrounds the Earth
What is the atmosphere?
100
1% of all the gases in the atmosphere
What are other gases?
100
78%
What the amount of nitrogen in the atmosphere?
100
The source of all the energy in our atmospehre
What is the sun?
100
The layer where weather occurs
What is troposphere?
200
Nitrogen and Oxygen
What are the most abundant gases on Earth?
200
mass/volume
What is the equation for density?
200
In terms of air pressure, the more the mass in a given volume of air......
What is greater air pressure?
200
Air has pressure because.....
What is air has mass?
200
Where are radio waves reflected back to Earth by ion particles?
What is ionosphere?
300
Three oxygen molecule bonded together. Absorbs harmful UV rays and is found in the stratosphere
What is ozone?
300
In terms of density, the less the mass in a given volume of air......
What is less dense?
300
The reason why our atmosphere is so important
What is provides all gasses that living things need to survive? or What is protects us from harmful UV radiation?
300
The reason why it is more difficult to breath at higher elevations than a the bottom of the troposphere
What is the oxygen molecules are spread out more?
300
The layer that has the lowest density and pressure. Gas molecules rarely strike each other
What is exosphere?
400
The chemical formula for ozone ....
What is 3 oxygen atoms bonded together
400
The reasons why the Greenhouse Effect is important
What is 9
400
Energy transfer by direct contact
What is conduction?
400
The layer that contains most of the atmosphere's mass
What is troposphere?
500
The reason why the density of the atmosphere decreases with altitude. Why?
What is Two reasons: 1. At higher altitudes, there is less air pushing down from above 2. Gravity is weaker farther from Earth's center. So at higher altitudes, air molecules can spread out more, and air density decreases
500
Characteristic of each layer of the atmosphere
What is..... Troposphere (has most of atmosphere's mass, 1st later next to Earth, weather occurs here) Stratosphere (contains ozone layer, temp increases as you increase in altitude) Mesosphere (burns up meteorites, very cold) Ionosphere (has particles that absorb sun's energy to create Northern Lights) Exosphere (particles so far apart they rarely strike each other, outermost layer of atmosphere)
500
The kind of energy exchanged when water changes from on state of matter to another
What is latent heat?
500
The comparison of the temperature of the stratosphere and the mesosphere....for full credit tell why
What is the stratosphere is warm and mesosphere is cold?
500
The layers of the atmosphere are classified by
What is differences in temperature?
