Question 16

What are faults

Answer 16

Vertical cracks in the rock

Question 17

Joints

Question 20

What is a bedding plane

Answer 20

The surface between two layers of sedimentary rock

Question 21

What is the surface between two layers of sedimentary rock

Answer 21

A bedding plane

Question 22

What happens to rocks with more joints and faults, or a bedding plane

Answer 22

They erode faster, more lines of weakness

Question 23

What is strata

Answer 23

Layers of rock

Question 24

What are layers of rock called

Answer 24

Strata

Question 25

What are the 2 types of coastline

Answer 25

Concordant and discordant

Question 26

What is a discordant coastline

Answer 26

Where the geology alternates hard rock and soft rock perpendicular to the coast

Question 27

What is it called when the geology alternates hard rock and soft rock perpendicular to the coast

Answer 27

A discordant coastline

Question 28

What is a concordant coastline

Answer 28

The same type of rock running parallel to the coastline

Question 29

What is it called when the same type of rock runs parallel to the coastline

Answer 29

A concordant coastline

Question 30

Explain the formation of headlands and bays

Answer 30

There is a discordant coastline, both the soft and hard rock is eroded by hydraylic action and abrasion, the soft less resistant rock erodes faster creating bays, the hard resistant rock erodes slower creating headlands which stick out into the sea leaving them more vunerable to further erosion
