The 4 main layers of the atmosphere are:
|
Troposphere, stratosphere, mesosphere, and thermosphere.
|
|
|
What is thermal conduction?
|
The transfer of thermal energy through a material.
|
|
|
What is convection?
|
The transfer of thermal energy by the circulation or movement of a liquid or gas.
|
|
|
What is radiation?
|
The transfer of energy as electromagnetic waves.
|
|
|
What are high and low air density?
|
The less the density, the lower the air pressure. The higher the density, the higher the air pressure.
|
|
|
What is air pressure?
|
It is the measure of the force with which air molecules push on a surface.
|
|
|
What are polar easterlies?
|
They are wind belts that extend from the poles to 60 degrees latitude in both hemispheres.
|
|
|
What are prevailing westerlies?
|
They are wind belts that are found between 30 and 60 degrees latitude in both hemispheres.
|
|
|
What are horse latitudes?
|
They are the places on earth at about 30 degrees north and south latitudes where sinking air creates an area of high pressure. The winds at these locations are weak.
|
|
|
What are trade winds?
|
They are winds that blow from 30 degrees latitude almost to the equator.
|
|
|
What are the percentages of each gas in our atmosphere?
|
78% Nitrogen
21% Oxygen 1% Other Gases |
|
|
What is ozone?
|
It is the layer of ozone gases in the stratosphere that block out the sun's UV rays. It could also be the ozone gases that come from pollution too.
|
|
|
What is land breeze?
|
A coastal breeze blowing at night from land to sea.
|
|
|
What is sea breeze?
|
A thermally produced wind blowing from a cool ocean surface onto adjoining warm land.
|
|
|
What is global warming?
|
It is the warming of the earth due to an increased amount of greenhouse gases in the air capturing heat.
|
|
|
What is the greenhouse effect?
|
It is when a filter of sorts allows the sun's energy and heat to come in but does not allow it to escape from out of the filter.
