EQ2 - 4.5

Question 1

Why is the sea level rising?

Answer 1

Sea level are rising due to thermal expansion - the increase in heat increases the energy in water particles, making them take up much more space.

Question 2

How bad will sea level get and how will it affect different places around the world?

Answer 2

The Antarctic ice sheet holds approximately 90% of freshwater in our planet, if melted due to rising temperatures, it could raise sea levels by 61.1 metres.

Should sea levels rise, a total of 100000 properties in the southeast of England will be at risk.

Question 3

How will climate change affect storms?

Answer 3

Storm surges will increase power if combined with sea level rise and if already worsened (hotter atmosphere).

Question 4

How do groynes work?

Answer 4

Groynes prevent longshore drift from moving sediment along the coast. It builds up beaches and absorbs wave energy.

Question 5

How do sea walls work?

Answer 5

Sea walls focus on reflecting wave energy back out to the sea raer than undercutting the cliff.
