Q

How are headlands and bays formed

A

When softer rock erodes faster than harder rock, creating bays and leaving headlands jutting out into the sea

Q

Describe the process of cave, arch, stack, and stump formation

A

Cave- hydraulic action and abrasion widen cracks in a headland
Arch- erosion deepens the cave until it breaks through the headland
Stack- the arch collapses, leaving a tall rock pillar
Stump- The stack erodes further and collapses

Q

Describe the formation of a wave cut platform

A

A wave cut platform forms when destructive waves erode the base of a cliff, creating a wave cut notch through processes like abrasion and hydraulic action. As the notch grows, the cliff above becomes unstable and collapses, leaving behind a flat platform.
