Q

What is convection current?

A
  • Warm air rises, because it is less dense than cooler air.
  • Cool air sinks, because it is more dense than warmer air.
  • Rising air creates low pressure.
  • Sinking air creates high pressure.

Q

How is air pressure created?

A

Air particles move from areas of high pressure to areas of low pressure.
This creates wind.

Q

What happens in insolation?

A

insolation from the sun varies considerably, places at low latitudes close to the equator have higher levels of insolation as the rays are spread over a smaller area.
At the poles (higher latitude) the sun’s rays are spread over a greater distance.

Q

What happens at 60 degrees north and south in global atmospheric circulation?

A
  • At about 60 degrees north and south, cold polar air mixes with warmer air and rises, creating a belt of low pressure.

Q

What happens at the equator in the global atmospheric circulation?

A
  • Suns heat is concentrated.
  • Warm air rises creating a belt of low pressure.
  • As the air rises it cools.
  • Clouds form and then release precipitation.
  • Above the air will eventually sperate and move to higher latitudes.
17
Q

What happens at 30 degrees north and south of the equator in global atmospheric circulation?

A
  • Cool air sinks creating a belt of high pressure.
  • As the air sinks it becomes warmer and drier.
18
Q

What happens at the North and South pole in the global atmospheric circulation?

A
  • Sun’s heat is spread out
  • Air cools and sinks, creating a belt of high pressure and a cold, dry climate.
19
Q
A
  • The Equator recieves much higher insoliation
