Question 6

Hadley cell

Answer 6

The movement of the air from the equator to the mid latitudes and back towards the equator

Question 7

Coriolis effect

Answer 7

The deflection of the global air circulation because of the rotation of the earth- to the left in the Southern Hemisphere and to the right in the northern hemisphere

Answer 9

(Hurricane, typhoon)

A region of very low air pressure that forms over warm oceans and has wind speeds often over 150 km/h

Question 10

Possible impacts of human induced changes to earth’s atmosphere include..

Answer 10

• ozone-destroying gasses
• rising levels of carbon dioxide from burning fossil fuels

Question 11

Climate conditions at different places around the earth are controlled by the

Answer 11

• Constant movement of air and water
• differences in the amounts of sunlight received because of location
• distribution of ocean and cintinents

Question 12

The earth’s most important source of energy

The sun

Question 13

The amount of solar radioactive reaching the earth is controlled by

Answer 13
