Question 13

What are the 5 steps of sand dune formation

Answer 13

Sand moved up the beach by the aeolian deposition, obstacles decrease wind speed so sand is deposited to form embryo dunes, embryo dunes are colonised by marram grass and roots stabilise the sand, sand stabilises forming foredunes and mature dunes, dune slacks can form in depressions in the sand

Question 14

What are dune slacks

Answer 14

Small pools in sand dunes

Question 15

What are small pools in sand dunes

Answer 15

Dune slacks

Question 16

How are sand beaches formed

Answer 16

Sand and shingle are deposited at the coasts, often in shetered bays, the waves entering the bay are constructive waves, which deposit sediment, a berm on the beach marks where the high tide line is and the extent to the water.

Question 17

How are pebble beaches formed

Answer 17

Sand and shingle are deposited at the coasts, which comes from nearby eroding cliffs, the deposited material becomes smaller and more rounded from destructive waves
