Question

please can you help me with this!

i need to know why north norfolk is under threat in general and stuff about long shore drift and fetch etc...

i also need to know why happisburgh and sheringham are at risk too

thankyou

Answer 1

This coastline offers “little resistance” to marine erosion due to the absence of igneous rocks and highland.

There are extensive areas are low lying land.

There is a population which is dependent on the sea (fishing, tourism, ports, retirement homes etc.) and therefore located in coastal locations.

Sections of coast are subjected to significant fetch (long travelled waves).

There is an increased frequency of winter storms.

Coastal protection agencies must prioritise sections of coastline - a point scoring system has been introduced to aid decision making.

Answer 2

the cliff sides are in danger of weathering and also erosion, where the sea water erodes the bottom of the cliff side causing an indent in the cliff and eventually the weight of the rock collapses taking off chunks of the cliff side which eventually will get worse and worse unless barriers are put up around the cliff sides in danger to stop the sea from comming in contact with the cliff surface.

hope this helps a bit ^^

Answer 3

Norfolk is made out of iron and it will go rusty if sea water lands on it

Answer 4

Most of the east coast is made of sedimentary deposits.  The Holderness coast is made of clay and certain areas of the Norfolk coast.  The heavy tides undermine the coast and collapses the soft material above.  The most extreme times coincide with rough weather and high tide and the extreme spring tide just multiplies this problem.  What you need to do is investigate is the composition of the areas you are talking about, you will find it is soft sedimentary deposits.  A good geological map is perhaps all you need to do this.  Areas such as Scotland which are made of Granite wear much less, over hundreds of years compared to a decade elsewhere.

Answer 5

Isn't it all due to costal erosion??  And also that a lot of the land there is reclaimed fenland?
