Atmosphere
A thin layer of air that forms a protective covering around the planet.
Troposphere
The lowest of Earth's atmospheric layers.
Stratosphere
The layer directly above the troposphere. A portion of the stratosphere is the ozone layer.
Mesosphere
Extends from the top of the stratosphere. One of the upper layers of the atmosphere.
Thermosphere
The thickest of earth's atmospheric layers. It's named for its high temperatures.
Exosphere
The highest atmospheric layer. Beyond this is outer space.
Ozone layer
Within the stratosphere, lies an atmospheric layer called the --------. This thing is made of oxygen.
Organism
Earth's early -------- released oxygen into the atmosphere.
Ozone hole
A hole in the ------ layer.
Ionosphere
Within the mesosphere and thermosphere is a layer of electrically charged particles called the ionosphere.
UV rays
Is one of the many types of energy that come to earth from the sun.
CFC's
The blame that some air pollutants are destroying the ozone layer falls on chlorofluorocarbons, which are chemical compounds.
Which layer protects us from UV rays?
The ozone layer
Which gas makes up the ozone layer?
Oxygen
How was the ozone layer created?
...
Why are most gases in the troposphere?
Because that's where we live.
Why is the mesosphere the coldest layer?
Because the temperature decreases with altitude.
Why is it difficult to train for a sport on the top of a mountain?
Because fewer molecules of air exist there.
Convection
Is the transfer of heat by the flow of material.
Conduction
Is the transfer of energy that occurs when molecules bump into each other.
Radiation
Energy that is transferred in the form of rays or waves.
Doldrum
The windless rainy zone near the equator.
Prevailing westerlies
Are responsible for much of the movement of weather across North America.
Trade winds
Air descending earths surface near 30 degrees north and south creates steady that in tropical regions.
Polar easterlies
Near the North Pole ----- blow from northeast to southwest.
Near the South Pole ------ blow from the southeast to the northwest.
Coriolis effect
�The rotation of Earth causes moving air and water to appear to turn to the right north of the equator and to the left south of the equator.
Land breeze
Movement of air toward the water from the land.
Sea breeze
Created during the day because solar radiation warms the land more than the water.
Specific heat
The amount of heat required to heat an object.
Ionosphere
A layer of electrically charged particles.
Atmospheric pressure
Have a mass, extend hundreds of km above earths surface,
Jet stream
Narrow belts of strong winds.
Which heat transfer occurs when 2 objects at different temperatures come in contact with each other?
Conduction
Name all 5 atmospheric layers.
Troposphere,Stratosphere, Mesosphere,Thermosphere, and Exosphere
Why is air pressure greater in the troposphere?
Because gravity pulls gases down
Why is the mesosphere the coldest?
Because the gases in it don't attract the Sun/UV rays.
How did oxygen come to make up 21 percent of earths present atmosphere?
Because early organisms released oxygen into the air
How does wind form?
Uneven heating of earths surface by the Sun causes some areas to be warmer than others
Why is a flight from Israel to NY longer than a flight to israel from NY?
Because of jet streams
Why does the equator receive more of the suns rays?
Because the Sun shines all year round
Why do sea breezes occur during the day, but not at night?
...
What deflects (moves) winds to the west or east?
The coriolis effect.
