Year 10 Geography 4.3 A

Question 1

What is the rock type like on a concordant coats line

Answer 1

The rock on a concordant coastline is a layer of hard rock like limestone or granite then a layer of soft rock further inland for example clays.
If starta are parallel to the coast line the coast is concordant

Question 2

What features are found on a concordant coastline

Answer 2

Concordant land has fewer headlands and bays compared to discordant lands
They have the same rock type parallel to the coastline

Question 3

What is the rock type like on a discordant coast

Answer 3

The rock type is made of soft rock which are clay and sand and hard rock being chalk and limestone.
If strata are at right angle to the coastline the coast is discordant

Question 4

What features are found on a discordant coast?

Answer 4

The soft rock ends up eroding much quicker then the hard rock forming headlands and bays
Discordant coastline have many different rock / rock layers are perpendicular to the coast

Question 5

What are joints and faults?

Answer 5

Joints are small normally vertical lines found in many rocks and faults are larger cracks caused by past tectonic movements where rocks have moved

Question 6

What is the difference between hard/soft rock? Give examples

Answer 6

What is the difference between hard/soft rock? Give examples

Question 7

Describe what are the characteristics of headlands and bays?

Answer 7

Headlands are usually hard rock while bays are usually soft rock
Since the soft rock gets eroded easily bays are further inland than Headlands

Question 8

Explain the stages in the formation of headlands and bays?

Answer 8

1. The sea attacks a section of coast with alternating bands of hard and soft rock.
2. The bands of soft rock erode more quickly than those of more hard rock.
3. This leaves a section of land jutting out into the sea called a headland
4. The areas where the soft rock has eroded away, next to the headland, are called bays.

Question 9

Describe what are the characteristics of wave cut platforms?

Answer 9

A wave-cut platform is a wide gently-sloping surface found at the foot of a cliff

Question 10

What are the characteristics of arch/stack/stumps?

Answer 10

.

Question 11

Explain how stumps are formed?

Answer 11

.

Question 12

How do joints and faults affect erosion?

Answer 12

The more joints and faults there are in a rock the weaker it is as water can erode it more easily.
