- polar easterlies
- between 60 degrees and 90 degrees latitudes
- gravity
- what pulls the atmosphere toward the surface giving it weight?
- jet streams
- a narrow belt of strong winds that blow in the upper troposphere
- air pressure
- the measure of the force with which air molecules push on a surface
- right
- in the northern hemisphere the winds curve to the what?
- radiation
- the transfer oof energy as electomagnetic waves
- conduction
- the transfer of energy as heat through a material
- trade winds
- blow between equator and 30 degree latitude
- doldrums
- an area of low pressure around the equator where the trade winds of the northern and southern hemisphere
- low pressure
- at the equator warm,less dense air rises and creates an area of what?
- left
- in the southern hemisphere the winds curve to the what?
- nitrogen
- this is the most abundant gas at 78% followed by oxygen at 21%
- high pressure
- at the poles cold,more dense air sinks and creates an area of what?
- mesosphere
- coldest layer of the atmosphere
- pressure belts
- uneven heating of the earth produces what that occur at about every 30 degrees latitude
- convection
- the transfer of thermal energy by the circulation movements
- electrically chagred particles
- the auroras occur in the ionosphere and produced by what?
- troposhpere
- lowest layer of the atmosphere
- global winds
- are part of a pattern of air circulation that moves across the earth
- local winds
- generally move short distances and can blow from any direction
- convection cells
- the circular patterns caused by the rising and sinking of air are called what?
- greenhouse effect
- the warming of the surface & lower atmosphere to the Eearth
- the temp.
- depends on the gases present,some gases absorb energy and cause an increase in what?
- temp.
- measures the average energy of particles in motion
- mountain & valley breezes
- caused by a difference in altitude and temp.
- global warming
- a gradual increase in average global temp.
- theremosphere
- the uppermost layer of the atmosphere
- horse latitudes
- an area of high pressure at about the 30 degree north and 30 degree south
- wind
- movemenbt of air caused by differences in air pressure
- 4 layers
- the atmosphere is divided into what based on the temp.?
- few and far apart & can't transfer much energy
- but the temp.does not feel hot b/c of what?
- atmosphere
- a mixture of gases that surrounds a planet or moon
- stratosphere
- the layer above the troposphere
- radiation balance
- the balance between incoming energy and outgoing energy
- westerlies
- prevailing wind belts that blow between 30 degrees and 60 degrees latitudes
- ozone
- a molecule that is made up of 3 oxygen atoms
