1.4 - Concordant Coasts And Geological Structure

Question 1

Describe a concordance coast:

Answer 1

The alternate layers run parallel to the coastline

Waves only therefore contact one rock type

Question 2

Geology of Dalmatia?

Answer 2

Limestone

Question 3

Layers of geology are arranged how?

Answer 3

Oldest at bottom

Youngest at top

Question 4

What do tectonics do to the layers?

Answer 4

Fold and compress layers into anticlines and synclines
Strata are titled vertically in some places
The pressure and cooling creates faults and cracks

Question 5

What happens to synclines and why?

Answer 5

Eroded and flooded due to SLR and rivers eroding them over time

Question 6

How does seawater get into synclines via anticlines?

Answer 6

Faulting and weak areas in anticlines

Question 7

What happens when synclines are eroded?

Answer 7

Parallel anticlines are left since these layers are higher up and more resistant

Question 8

What do rivers do to anticlines?

Answer 8

Erode the top of them, flattening the top, giving a more band-like appearance
