How Mass Movement Creates Distinctive Coastal Landforms

Question 1

Slumping involves the movement of

Answer 1

saturated soil and weak rock along a curved slip plane.

Question 2

Slumps can create

Answer 2

steep backscarps and terraced slopes, such as those seen at Barton-on-Sea in southern England

Question 3

Rockfalls occur on

Answer 3

steep, hard rock cliffs when material is loosened by weathering (e.g., freeze-thaw). Gravity causes the rocks to fall and accumulate at the base of the cliff.

Question 4

Rockfalls contribute to the formation of

Answer 4

scree slopes or talus piles at the base of cliffs

Question 5

Landslides involve the

Answer 5

rapid movement of large blocks of rock or earth downslope, often triggered by heavy rainfall or coastal erosion

Question 6

Landforms Created: Landslides can lead to

Answer 6

the collapse of coastal cliffs, creating steep cliffs or headlands

Question 7

Mudflows occur when

Answer 7

saturated fine-grained sediments flow downslope due to gravity. This is common on coastlines with unconsolidated material, such as glacial deposits.
