Formation of Coastal Features Quiz

What natural process is responsible for the formation of a sea cave?

• Erosion

• Deposition

• Sedimentation

• Weathering

Which type of erosion involves waves throwing beach materials against the cliff?

• Corrosion

• Solution

• Attrition

• Abrasion

What is the role of hydraulic action in coastal erosion?

• It smoothens rocks by rolling them.

• It forces air into cracks causing small explosions.

• It deposits sediments on the shore.

• It dissolves rocks in the water.

How is an arch formed from a sea cave?

• By deposition of sediments

• By erosion on both sides of the headland

• By volcanic activity

• By human intervention

What eventually causes the roof of an arch to collapse?

• Erosion by wind

• Earthquake activity

• Increased wave deposition

• Gravity and lack of support

What is left behind after the roof of an arch collapses?

• A stack

• A dune

• A cave

• A beach

What process leads to the formation of a stump from a stack?

• Erosion by waves

• Tectonic uplift

• Sediment deposition

• Wind erosion

Which feature is formed first in the sequence of cave, arch, stack, and stump?

• Stump

• Arch

• Stack

• Cave

What is the primary cause of erosion in the formation of these coastal features?

• Wind

• Ice

• Rain

• Waves

Which of the following is NOT a process involved in the formation of coastal features?
