Coastlines

Coastal erosion...

• causes the tides

• is where the sea wears away at the land

• is how waves are created

Select 4 processes of coastal erosion.

• Hydraulic Action

• Corrosion

• Attrition

• Nutrition

• Abrasion

Hydraulic-Action is...

• where large rocks collide causing them to break down into the smaller rocks

• where waves pick up rocks and hurl them at the cliff causing it to break down.

• where acids in the water dissolve the cliff.

• where waves push air and water into cracks in the cliff forcing it to break apart.

Corrosion is...

• where large rocks collide causing them to break down into the smaller rocks

• where waves pick up rocks and hurl them at the cliff causing it to break down.

• where acids in the water dissolve the cliff.

• where waves push air and water into cracks in the cliff forcing it to break apart.

Attrition is...

• where large rocks collide causing them to break down into the smaller rocks

• where waves pick up rocks and hurl them at the cliff causing it to break down.

• where acids in the water dissolve the cliff.

• where waves push air and water into cracks in the cliff forcing it to break apart.

Abrasion is...

• where waves pick up rocks and hurl them at the cliff causing it to break down.

• where acids in the water dissolve the cliff.

• where waves push air and water into cracks in the cliff forcing it to break apart.

Bays are formed because...

• they are made up of soft rock, which erodes faster than hard rock

• they are made up of hard rock, which erodes slower than soft rock

Headlands are formed because...

• they are made up of soft rock, which erodes faster than hard rock

• they are made up of hard rock, which erodes slower than soft rock

Select the correct order of formation.

• Stack > Stump > Cave > Arch

• Arch > Stump > Stack > Cave

• Cave > Arch > Stump > Stack

• Cave > Arch > Stack > Stump

The most damage occurs when there is...

• Low tide and large waves

• High tide and small waves

• High tide and large waves

• Low tide and small waves
