Erosional Processes Quiz

What is the first type of erosional process that occurs when waves hit a cliff?

• Attrition

• Solution

• Hydraulic action

• Abrasion

What happens to large rocks during the process of attrition?

• They break into pieces

• They become smaller and rounder

• They become larger

• They stay the same size

What does hydraulic action do to the cliff?

• It causes the cliff to grow taller

• It adds more rocks to the cliff

• It dissolves the cliff

• It compresses air inside weaknesses and cracks

What is the fourth type of erosion mentioned in the video?

• Solution

• Abrasion

• Hydraulic action

• Attrition

What is the main factor causing erosion in hydraulic action?

• Force of the wind

• Force of the wave

• Force of gravity

• Force of the sun

What does abrasion cause to appear at the base of the cliff?

• A wave cut cave

• A wave cut platform

• A wave cut arch

• A wave cut notch

What does attrition do to the rough edges of rocks?

• It makes them smoother

• It makes them sharper

• It has no effect on them

• It knocks them off

What is the result of the repeated hitting of waves against the cliff in hydraulic action?

• Strengthening of the cliff

• Erosion of the cliff

• Formation of new rocks

• Expansion of the cliff

What is the force of the wave doing when it hits the cliff in hydraulic action?

• All of the above

• Causing expansion of the cliff

• Causing compression of air

• Causing erosion

What is the main cause of erosion in abrasion?

• Force of gravity

• Force of the wave

• Force of the wind

• Force of the sun
