energy that is radiated or transmitted in the form of rays or waves or particles
Energy from the sun
20%-absorbed by ozone,clouds,and atmospheric gases
25%-scatered and reflected by clouds in the air
5%-reflected by earths surface
50%-absorbed by earths surface
currents are created as warm air rises and cool air sinks.
near the earths surface air is heated
a current caused by the rising of heated fluid and sinking of cooled fluid
the green house effect
1-short wave solar energy passes through the atmosphere and is absorbed by clouds and the earths surface
2-clouds and earths surface reradiate the solar energy as long-wave energy
3-the long-wave energy warms earth and the atmosphere
the warming of the surface and lower atmosphere of earth that occurs when water vapor carbon dioxide and other gasses absorb and reradiate thermal energy
the balance between incoming energy and outgoing energy
a gradual increase in average global temperature
the movement of air caused by differences in air pressure
the large, circular patterns caused by the rising and sinking of air.
separate bands of high and low pressure, found about every 30 degrees of latitude
The apparent curving of the path of a moving object from an otherwise straight path due to the earth's rotation
patterns of air circulation
prevailing winds that blow from east to west between 60 degrees and 90 degrees latitude in both hemispheres
prevailing winds that blow from west to east between 30 degrees and 60 degrees latitude in both hemispheres
Prevailing winds that blow northeast from 30 degrees north latitude to the equator and that blow southeast from 30 degrees south latitude to the equator
The area where trade winds of the Northern and Southern Hemispheres meet in an area around the equator
A narrow belt of strong winds that blow in the upper troposphere and lower stratosphere
these winds move short distances and can blow from any direction. EX: Mountain Breezes and Valley Breezes
A mixture of gases that surrounds a planet or moon.
What does the atmosphere made up of?
Mostly nitrogen, 21% oxygen and 1% of argon, carbon dioxide, water vapor and other gases
What does the atmosphere do for us?
Gives us oxygen to breathe and protects us from the sun's damaging rays
The measure of the force with which air molecules push on a surface
Is what holds the atmosphere in Earth
How many layers does the atmosphere have?
Four: Troposphere, stratosphere, mesosphere and thermosphere (TSMTh)
the lowest layer of the atmosphere, in which temperature drops at a constant rate as altitude increases; the part of the atmosphere where weather conditions exist (layer where gases turn and mix) (contains 90% of the atmosphere's total mass)
the layer of the atmosphere that is above the troposphere and in which temperature increases as altitude increases (gases are layered and do not mix very much)
the layer of the atmosphere between the stratosphere and the thermosphere and in which temperature decreases as altitude increases (middle layer and the coldest layer)
the uppermost layer of the atmosphere, in which temperature increases as altitude increases (where temperature are highest)
a layer in the stratosphere (at approximately 20 miles) that contains a concentration of ozone sufficient to block most ultraviolet radiation from the sun (protects life on Earth by absorbing harmful ultraviolet radiation)
Measure of the average energy of particles in motion
Shimmering lights resulting from Ions radiating energy
