Coastal classification

Question 1

Rocky Coastlines Properties

Answer 1

High energy environments
Rate of Erosion>Rate of depositions
Erosional Landforms: Headlands, cliffs, shoreline platforms
UK=Atlantic facing coastline e.g Cornwall, Northern/Western Scotland

Question 2

Sandy Coastline Properties

Answer 2

Low wave energy environments
Waves are less powerful
Rate of deposition>Rate of erosion
Landforms: Beaches, spits or coastal Plains
Vegetation=stabilisation

Question 3

What is an Estuarine?

Answer 3

Low energy environment
Mouth of rivers (Mudflats and salt marshes) sheltered

Question 4

Levels of energy - Role in classification

Answer 4

high/low

Question 5

Geology - Role in classification

Answer 5

Estuarine Coastline = Sedimentary rock
Rocky Cliff coastline = sedimentary rock
Sandy coastlines= igneous/metamorphic rock
Concordant coastline = Strata layers are horizontal
Discordant coastline= Strata layers are vertical.

Question 6

Dominant processes - Role in classification

Answer 6

Erosion
Deposition

Question 7

Sea level rise - Role in classification

Answer 7

Emergent coasts: Land rises faster than sea level rises globally

Submergent coasts: Flooded coasts due to sea level rises or land sinking locally

Question 8

Formation process - Role in classification

Answer 8

River depth
Marine coastline

Question 9

Tidal Range types - Role in classification

Answer 9

Micro or macro
