Answer 1

Wearing away / break down and removal of material in this case by the sea

Question 2

Solution

Answer 2

Dissolving of soluble chemicals in rocks

Question 3

Corrosion

Answer 3

Fragments of rock picked up and hurled by sea at cliff

Question 4

Abrasion

Answer 4

Sand paper affect of pebbles grinding a rocky platform causing it to become smooth

Question 5

Attrition

Answer 5

Rock fragments carried by sea knock against each other causing them to become smaller and rounded

Question 6

Hydraulic action

Answer 6

Power of waves smash into cliff forcing air into holes and cracks in rock. Eventually break apart

Question 7

Transportation

Answer 7

Movement of eroded material

Question 8

Traction

Answer 8

Large pebbles rolled along sea bed

Question 9

Question 10

Suspension

Answer 10

Question 11

Solution

Answer 11

Dissolved chemicals often derived from limestone or child

Question 12
