|
Thermosphere, Mesosphere, Stratosphere, troposphere.
|
|
The trnsfer of energy as heat through a material.
|
Conduction
|
|
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 dense and warmer the surrounding air rises.
More dense and colder so air sinks. |
|
Caused by unequal heating of the earth.
|
Air Pressure.
|
|
Polar easterlies.
|
WInd belts that extend from the poles to 60 degrees latitude in both hemispheres.
|
|
Pevailing Westerlies
|
Prevailing winds that blow from west to east between 30 & 60 degrees latitude in both hemispheres.
|
|
At about 30 degrees noth and 30 degrees soth latitude, sinking air created and area of high pressure. The winds at these locations are weak.
|
Horse latitudes.
|
|
Trade winds
|
In both hemisperes, the winds that blow from 30 degrees latitude almost to the equator.

|
Sea Breeze
|
Wind blow from sea to land during nightime hours.
|
|
Ozone layer
|
Stops uv rays from reaching earths surface.
|
|
Global warming
|
a gradual increase in average global temperature
|
|
