the cycle of air

Question 1

what are the two parts of this cycle in relation to landforms

Answer 1

the poles and the equator

Question 2

explain the temp at the poles and equator

Answer 2

at the poles, the temperature is very cold and therefore air temperature is low, while at/around the equator the temperature is much higher and therefore the air temperature is higher

Question 3

we know that hot air rises and cold air sinks, but why

Answer 3

hot air is less dense than cold air. this is because the kinetic energy involved in hot air causes the particles to move around at a much faster rate than in cold air.

in cold air, the particles move very slowly and so there is often more of them as there is more space due to them moving slowly.

therefore more particles means that cold air is more dense and will fall due to gravity and hot air will rise as it is far less dense

Question 4

explain the cycle that this hot and cold air creates

Answer 4

1. the hot air at the equator will start to rise upwards towards the poles
2. once it reaches the poles the hot air will be cooled due to freezing temperatures
   3.this cool air will start to fall back down towards the equator
3. this cycle continues

Question 5

draw a diagram to show this cycle

Answer 5

check book

Question 6

what is atmospheric circulation

Answer 6

Atmospheric circulation is the large-scale movement of air and is responsible for the distribution of thermal energy across the surface of the Earth

Question 7

what are three of the main atmospheric cells called

Answer 7

hadley, ferrel and the polar cells

Question 8

what are easterliers

Answer 8

winds blowing west

Question 9

what are westerlies

Answer 9

winds blowing east

Question 10

what cell is located at the poles

Answer 10

polar cells

Question 11

what cell is located at the equaltor

Answer 11

hadley cell

Question 12

what cell is located in the middle of the two other cells

Answer 12

Ferrel cells are located between polar and hadley cells

Question 13

what is the largest cell

Answer 13

hadley cells

Question 14

explain low pressure

Answer 14

Areas of low pressure, including the equatorial low pressure system at the equator and the subpolar low pressure systems in the north and south, are typically associated with unstable, inclement weather which is cloudy and windy, with a chance of rain or possible storms

Question 15

explain high pressure

Answer 15

areas of high-pressure, such a subtropical Impala hide in the north and south, typically associated define stable condition, and clear skies
