Global atmospheric circulation

Question 1

What is Global atmospheric circulation

Answer 1

The movement of air across the planet occurs in a specific pattern.

Question 2

What are the 4 main features of global atmospheric

Answer 2

1) The transfer of heat from the Equator to the poles
2) There are 3 circulation cells - Hadley, Ferrel and Polar
3) Jet streams impact on the movement of heat energy
4) The spin of the earth creates the Coriolis effect

Question 3

What is the main source of heat energy for the world

Answer 3

The sun

Question 4

The sun heats the earth how

Answer 4

Unevenly, It heats more at the equator than at the poles

Question 5

The uneven heating of the Earth creates a heat surplus and deflect. Where is the surplus and deficit found

Answer 5

The heat surplus ifs found at the equator and the deficit is found at the poles

Question 6

What two ways is heat energy transferred

Answer 6

1) Circulation cells

2) Ocean currents

Question 7

Where does the cold air move towards

Answer 7

The warm equator

Question 8

Where does the warm air move towards

Answer 8

The cold poles

Question 9

Explain what happens in low pressure

Answer 9

Low pressure is where HOT air rises creating low pressure on the ground. The rising air cools and condenses as it gets higher which creates clouds which make rain

Question 10

Explain what happens in high pressure

Answer 10

High pressure is where COLD air sinks creating more pressure on the ground. This pressure means that the air is unable to rise meaning no clouds form which means there is no rain
