How Do Coastal Erosion And Sea Level Change Alter The Physical Characterstics Of CL And Increase Risk

Question 1

Tsunami/storm surges

Answer 1

Flood low lying coastal plains in flood water but they can have a massive impact on the landscapes, washing away unconsolidated material

Question 2

Isostatic

Answer 2

Change in land height

Question 3

Glacial rebound (Isostatic)

Answer 3

As glaciers have melted in the NW of the UK, which were covered in ice sheets 3-4km thick, as they melt, the land starts to expand and readjust cuz the pressure is released off it. However, in the SE of the UK, where there weren’t any heavy glaciers, the rising of the NW caused a falling in land height in the SE

Question 4

Submergent coastform

Answer 4

Rias= river valleys and estuaries r flooded by rising eustatic sea levels
Fjords= glacial valleys r flooded
Dalmatian

Question 5

Dis of human management

Answer 5

Can slow down coastal recession but can speed it up elsewhere cuz if u do one intervention within a sediment or coastal system, this will have an impact further else along it

Question 6

How r humans contributing to RSL

Answer 6

Increasing pop and econmic activity in coasts, more people r living on the flat coastal plains which r marginal lands, the protection and magament can be increasing risk or reducing risk as levels of development have increased in coastal locations, therefore when recession occurs it is likely to increase econmic losses

Question 7

Low lying atolls at risk

Answer 7

Tuvalu, Maldives- climate refugees will move to mainland countries e.g. NZ

Question 8

Why are development unequal

Answer 8

Developed nations like Holland can put prevention in place whereas Bangladesh can’t
