Coastal processes

What is this the definition of?

"Where water and air are forced into cracks in the cliff face, exerting pressure and breaking it apart"

• Hydraulic action

• Abrasion

• Saltation

• Attrition

What is the obvious coastal landform in the background of this photo?

• Headland

• Arch

• Stack

• Bay

Which of these words is NOT associated with wave formation

• Elliptical

• Swash

• Backwash

• Traction

What is this the definition of?

"The movement of very small sediment (e.g. sand grains) through a bouncing or hopping motion"

• Attrition

• Traction

• Suspension

• Saltation

Which process is both a type of erosion and a type of transportation?

• Attrition

• Deposition

• Abrasion

• Solution

____ movement is the downward movement or sliding of material under the influence of gravity

Which type of mass movement is shown in this image?

• Rockfall

• Mudflow

• Rotational slumping

• Destructive

Over time and with further erosion and weathering, what will this coastal landform become?

• Stay as a stack

• Turn into a stump

• Become a wave cut platform

• Form an arch

What process causes the arch roof to collapse?

• Erosion by the waves

• Weathering

• It will not collapse - the rock is too strong

Longshore drift is the ______ movement of sediment along the coastline caused through transportation by waves
