• Solution

What is the term for rocks and pebbles crashing into each other, becoming smaller and rounder?

• Attrition

• Solution

• Erosion

• Abrasion

Which type of erosion involves rocks and sand scraping against cliffs, wearing them down?

• Solution

• Deposition

• Abrasion

• Hydraulic action

What happens during solution?

• Waves throw rocks at cliffs.

• Rocks dissolve in seawater.

• Air is forced into cracks.

• Sediment is deposited on beaches.

Which factor does NOT affect the rate of coastal erosion?

• Type of rock

• Strength of the waves

• Wind direction

• Temperature

What is coastal deposition?

• The breaking down of rocks.

• The transportation of sediment.

• The dropping of material carried by waves.

• The process of water dissolving rock.

What type of wave is most likely to cause deposition?

• Destructive wave

• Tsunami wave

• Constructive wave

• Tidal wave

What landform is created when sand and shingle are deposited along the coastline?

• Cliff

• Spit

• Arch

• Stack

Why do beaches form in sheltered areas?

• The waves lose energy and deposit sediment.

• Erosion is faster in these areas.

• Wind carries the sediment to these places.

• The area is too steep for waves to reach.

Which of the following is a landform created by the deposition of sand by the wind?

• Stack

• Cave

• Sand dune

• Wave-cut platform
