1.5 Earthquake Case Study

Question 1

Formation of Tsunamis

Answer 1

1. Tectonics plates movement can trigger an underwater earthquake​
2. The underwater earthquake causes shockwaves/ tremors which cause waves​
3. The wave increases in height over a large distance. ​

Question 2

formation of a tropical storm

Answer 2

Tropical storms develop over large surfaces of warm sea water 26 degrees or higher within the tropics between 5 and 20 degrees of the equator.​

​

Warm air rapidly rises from the surface of the sea which creates extreme low pressure. ​

​

The rotation of the earth, called the coriolis force, causes this air to spin. ​

​

As the air spins and warm air rises, more air rushes to fill the space left create strong surface winds. There is a calm, clear eye of the storm in the centre as this is the only part where cold air is sinking. ​

​

Warm air which has risen, cools and condenses to form huge cumulonimbus clouds which bring heavy rain. ​

​

Tropical storms move in the direction of the prevailing wind which are the common wind direction caused by the earth’s rotation (Coriolis effect)​

​

As hurricanes move inshore, their power gradually reduces because their energy comes from sucking up moist sea air.​

Question 3

what are short term impacts?

Answer 3

Short-term impacts refer to the immediate consequences or effects that occur shortly after a specific event or situation.

Question 4

what are long term impacts?

Answer 4

Long-term impacts refer to the lasting consequences or effects that occur over an extended period following a specific event or situation.
