4 main layers of the atmosphere
|
Toposphere, Stratosphere, Mesosphere, and Thermosphere
|
|
conduction
|
the transfer of energy as heat through a material
|
|
convection
|
the transfer of thermal energy by the circulation or movement of a liquid or gas
|
|
radiation
|
the transfer of energy as electromagnetic waves
|
|
high and low air density
|
the less the density, the lower the air pressure. the more density, the higher the air pressure is.
|
|
air pressure
|
caused by the unequal heating of the earth
|
|
polar easterlies
|
prevailing winds that blow from east to west between 60-90 degress latitude in both hemispheres
|
|
prevailing westerlies
|
prevailing winds that blow from west to east between 30-60 degrees latitude in both hemispheres
|
|
horse latitudes`
|
at about 30 degress north and 30 degrees south latitude, sinking air creates an area of high pressure
|
|
trade winds
|
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
|
|
percent of each gas in our atmosphere
|
78% nitrogen, 21%oxygen, 1% remaining
|
|
land breeze
|
during the day, when the air is warmer, the air pressure is low. during the night, when the air is cooler, the air pressure is high
|
|
sea breeze
|
during the day, the ocean is cooler, which will have high pressure. at night, the ocean is warmer, having low pressure
|
|
global warming
|
a gradual increase in average global temperature
|
|
greeanhouse effect
|
the warming of the surface and lower atmosphere of earth that occurs when water vaopr, carbon dioxide, and other gases absorb and reradiate thermal energy
|
|
ozone layer
|
stops UV rays from reaching earths surface
