Question

move each feature to to the appropriate category based on the process and causes of formation.
erosion by waves
deposition by waves
beach
sea arch
sandbar
barrier island
sea stack
wave - cut cliff

Explanation:

To solve this, we analyze each coastal feature:

Erosion by Waves (forms features via wearing away rock/land):

• Sea arch: Formed when waves erode a hole through a headland.
• Sea stack: Remains after a sea arch collapses, leaving an isolated rock.
• Wave - cut cliff: Created as waves erode the base of a cliff, causing the upper part to collapse.

Deposition by Waves (forms features via depositing sediment):

• Beach: Formed by wave - deposited sand, gravel, etc.
• Sandbar: A ridge of sand deposited by waves, often parallel to the shore.
• Barrier island: A long, narrow island formed by wave - deposited sediment, running parallel to the mainland.

Answer:

Erosion by Waves:

• sea arch
• sea stack
• wave - cut cliff

Deposition by Waves:

• beach
• sandbar
• barrier island
