Comparing cliff structures

Question 1

Horizontal dip

Answer 1

Uniform layers of bedding of planes produce steep sided cliffs

Question 2

Seaward Dip - Low angle

Answer 2

Joints opened by weathering and pressure release slabs to form cliffs dipping seaward. (<45*)

Question 3

Seward dip - high angle

Answer 3

Rock slabs slide down the cliff along bedding planes to form steep seaward dipping cliffs.

Question 4

Landward Dip

Answer 4

Bedding planes dipping produce stable, steep cliffs.

Question 5

How does the direction of dip affect the cliff profile?

Answer 5

Inland= More stable, less erosion
Seaward= Less strata, more erosion.

Question 6

How does the resistancey of rock to erosion affect the cliff profile.

Answer 6

Concordant/discordant or sea level

Joints; faults; folds (tectonic activity)
Lithology (rock type)
