Q6: Put these statements in order to describe freeze-thaw weathering.1. The fragments may then be deposited

as scree at the foot of a slope.2. If the air temperature drops below

freezing, the water will freeze and expand putting pressure on the rock.

3. Water, eg from rainfall or melting snow and ice becomes trapped in a crack or joint in the rock.

4. Over time the rock will weaken and eventually shatter into angular fragments.

Q17: What is the name given to these chalk stacks in Dorset?A. Old Charlie RocksB. Old Henry RocksC. Old Harry RocksD. Old Kenny Rocks

Q18: Which picture has the correct labels of headland formations?

Stump

Cave Headland

Beach Stack

Arch Headland

BayA B

Q19: Fill in the missing gaps that will give you a possible 6 mark answer to the question below.

Using an example, describe and explain the coastal formations found on a headland. [6]

The Foreland, a chalk headland on the _____Coast has all of the features of an eroded headland (caves, arches, stacks and stumps). Old Harry, is a particularly famous example of a _____ and Old Harry's Wife is an example of a stump. These features are formed when a headland is eroded by the waves - by _______________ and solution, particularly along lines of weakness in the rock. The erosion of a headland begins as erosion exploits a weakness in a rock forming a ____. If the weakness runs through the headland, two caves may form back to back, eventually forming an ____, an opening which passes right through the headland. Wave attack continues at the base of the arch, whilst weathering processes such as _________ attack the roof of the arch until it eventually collapses leaving a stack (an isolated column of rock). Again this is attacked by weathering and erosion processes until it collapses leaving the base, which forms a ______.

1. arch 2. cave 3. Dorset 4. freeze-thaw 5. hydraulic action 6. Norfolk 7. stump 8. stack

Q20: On this picture, which direction is long-shore drift?

Q35: Why are there plans to move some people out of Mundesley?

A. Mundesley is suffering severe erosion at the moment, and it is too expensive to build coastal defences.

B. If Mundesley is protected into the long-term, it will hinder natural processes and cause severe erosion elsewhere, so they will eventually realign the defences.

C. Mundesley is a run-down place which is of little economic value.

D. There are plans to build coastal defences elsewhere on the coast, which will have a severe impact on Mundesley.
