Exploring Wave Erosion and Coastal Landforms

The video tutorial explains four examples of coastal sea wave erosion: sea stacks, sea arches, sea caves, and headlands. Sea stacks are formed from resistant rock columns left behind after waves erode the mainland. Sea arches develop when wave action erodes sea caves until arches are formed. Sea caves are created when waves cut large holes into weak rock at the base of sea cliffs. Headlands are finger-shaped projections formed when hard rock erodes more slowly than surrounding softer rock, leading to the creation of bays.

What are sea stacks?

• Sedimentary rock formations

• Finger-shaped projections of hard rock

• Columns of resistant rock connected to the mainland

• Large holes in fractured rock

How do sea arches form?

• By the erosion of headlands

• By the accumulation of sediment

• By wave action cutting through sea caves

• By the erosion of sea stacks

What causes the formation of sea caves?

• Wave action cutting large holes into weak rock

• Erosion of hard rock

• Formation of sea stacks

• Sediment deposition

What are headlands?

• Columns of resistant rock

• Sedimentary rock formations

• Finger-shaped projections of hard rock

• Large holes in fractured rock

How do headlands form?

• By wave action cutting through sea caves

• By the accumulation of sediment

• By the erosion of sea stacks

• By the erosion of softer rock surrounding hard rock
