EQ3-4.5

Question 1

Why is the sea level rising and the coast flooding?

Answer 1

• Higher temperature causes water to expand in volume causing sea level to rise
• The higher temperature causes ice to melt and therefore more water in the sea so higher sea levels will be present

Question 2

Why will storms get worse with climate change?

Answer 2

The rising temperature causing warmer water which means storms will get more energy and can travel further

Question 3

How will storms and sea level rise affect erosion rates?

Answer 3

Storms give the rocks more erosional power-areas of hard rock will be more vulnerable to erosion and areas of soft rock will erode more rapidly

Question 4

How will storms and sea level rise affect people and the environment?

Answer 4

It will cause major floods and groynes or any coastal protection is destroyed due to the sea level rise

Question 5

Explain how groynes work?

Answer 5

Groynes trap sediment and builds up sediment in the beach to protect it from erosion

Question 6

Explain how sea walls work

Answer 6

Sea walls absorb the wave energy and reflect it out to the sea

Question 7

Explain how beach replenishment works

Answer 7

Sand is deposited on the beach by humans and this builds up protection for the beach leading to much less erosion

Question 8

What are the benefits and costs of slope stabilisation?

Answer 8

Slope stabilisation prevents mass movement by increasing the strength of the slope
The negative is that it is generally very expensive to install and difficult

Question 9

Explain how slope stabilisation works

Answer 9

There is a drain fitted into the slope that drains out the water from the slope. This strengthens the slope and stops rotational slumping
