Answer 6

Carbon dioxide
Methane
Nitrous Dioxide

Question 7

What is the name for the sea expanding due to warmer temperatures?

Answer 7

Thermal expansion

Question 8

What are the 3 different names for tropical storms?

Answer 8

Hurricanes
Cyclones
Typhoons

Question 9

What is precipitation?

Answer 9

Any liquid or frozen water that falls from the atmosphere. This could be in the form of rain, sleet, hail or snow

Question 10

What does ITCZ stand for?

Answer 10

InterTropical Convergence Zone

Question 11

What latitude is the Haldey Cell found between?

Answer 11

0 and 30 degrees North and South of the equator

Question 12

What latitude is the Ferrel Cell found between?

Answer 12

30 and 60 degrees North and South of the equator

Question 13

What latitude is the Polar Cell found between?

Answer 13

60 and 90 degrees North and South of the equator

Question 14

What minimum temperature is needed for tropical storms to form?

Answer 14

Minimum 26.5 degrees C

Question 15

What is the eruption theory?

Answer 15

Big volcanic eruptions have an affect on the Earth’s climate. They produce ash and sulphur dioxide which creates a blanket that stops sunlight reaching the Earth’s surface, lowering the overall temperature

Question 16

Name the scale that measures the strength of tropical storms

Answer 16

Saffir-Simpson Hurricane Scale

Question 17

What weather hazards do tropical storms bring?

Answer 17

Strong winds
Storm surges (and coastal flooding)
Intense heavy rainfall
Landslides

Question 18

What Category tropical storm is the highest?

Answer 18

Category 5

Question 19

What environmental factors are needed for a tropical storm to form?

Answer 19

Warm ocean temperatures of at least 26.5 degrees C
Strong winds
Coriolis force

Question 20

How does a tropical storm form?

Answer 20

1. Warm air from above the ocean rises
2. The warm air being drawn upwards brings with it water from the ocean which condenses to form cumulonimbus clouds
3. The air cools and condenses causing the air to fall, creating the eye of the storm
4. The Coriolis force causes the rising air to spiral around the eye of the storm
5. As the storm starts to move it gains energy from feeding off of the new warm water
6. Once the storm reaches land (makes landfall) it loses energy
