Question 2

currents

Answer 2

the parts of a beach, moving continuously in a certain direction

Question 3

Answer 3

the wearing away of Earths’s surface by factors such as wind and water

Question 4

desposition

Answer 4

the process where the material being transported by a wave is desposited

Question 5

swash

Answer 5

the act of waves carrying sand/pebbles/debris. ont the shore

Question 6

backwash

Answer 6

the movement of water back down the beach to the sea

Question 7

tides

Answer 7

very long-period waves that move through the ocean in response to the gravity pull of the moon.

Question 8

constructive/destructive waves

Answer 8

constructive waves are those that build up sediment on the beach (deposition) ad destructive waves are those that carry sediment away from the beach (erosion).

Question 13

What are some management strategies for Redhead Beach?

Answer 13

Redhead Beach has many management strategies in place. Walkways to the beach with rubber matting, as well as ‘dune fences’ to trap sand and help build the dunes have been implemented as a way to reduce erosion in the dunes. There are signs, fences, and public bins everywhere to reduce littering and trespassing on areas which shouldn’t be accessed. A ‘land care’ group also helps with the management of this beach and its dunes. In the dunes, these volunteers revegetate the plants as well as get rid of invasive species and weeds. A ‘habitat corridor’ has been implemented to close the gap between industrialised areas in order to allow migrating animals across. To trap and filter storm water before going back into the ocean, a ‘gross pollutant trap’ was added to Redhead Beach as well.
