Coastal morphology

Question 1

What is a discordant coastline?

Answer 1

Have alternating bands of hard and soft rock which are perpendicular to the
AKA Atlantic coasts
Form headlands and bays

Question 2

What is a concordant coastline?

Answer 2

Have alternating bands of hard and soft rock which are parallel to the coast
AKA Pacific coasts

Question 3

What are dalmatian coasts?

Answer 3

Made up of offshore islands and coastal inlets running parallel to the coastline,

Formed from concordant coastlines

Question 4

Describe a dip

Answer 4

Angle the rock layer forms with horizontal bedding plane

Question 5

What is a bedding plane?

Answer 5

Flat-lying surfaces that separate distinct layers of sediment

Question 6

How do bedding planes contribute to cliff profiles?

Answer 6

Bedding planes that dip towards the sea = gentler cliff profile (vulnerable to landslides)

Bedding planes that dip towards the land= steeper cliff profile (vulnerable to erosion)

Question 7

What are joints and faults?

Answer 7

Weaknesses within the rocks created by deformation.

Rocks with many are susceptible to the processes of erosion and weathering.

This is because these processes exert forces on the weaknesses

Question 8

What is coastal morphology?

Answer 8

The shape and structure of coastal systems or subsystems
