Stacks are pillars of rock standing out at the end of a headland. This stack was first formed when an arch collapsed leaving the stack behind. As seen in figure 1.1 this stack is mostly made out of basalt and a base of sandstone. also has a small amount of foliage on top.
This wave cut platform was formed over time by the cliffs slowly wearing away leaving behind this rock platform. It slopes from the high tide mark to the low tide mark.
Over time the cliffs have slowly collapsed, as the wave smashed against them, slowly they fall into the sea leaving steep cliffs behind. As seen in figure 1.1 these cliffs consist of basalt.
Over time small bits of rock and sand picked up by the water scratches against the cliffs, this slowly erodes the cliff and causes a cave to form which can be seen in figure 1.2.
Every time a wave smashes against the cracks in the cliff this forces air up the cracks which causes the cracks to expand eventually causing chunks of rocks to break off, this can cause cliffs like the one seen in figure 1.2.
Every time a large wave comes in it causes the rocks on the beach seen in figure 1.2 to smash into each other causing them to break apart and become smaller.
Over long periods of time, little bits of rock are slowly broken up. These small grains of sand that are the left overs of the rock are carried through the sea and are eventually deposited. When the grains are deposited they are normally deposited on the coast. This for s beachs like the one in figure 2.1
When sand is being deposited on the coast dunes will build up because the sand deposited on the beach gets blown up forming the dunes. Dunes are large hills of sand above the high tide mark. They are normally covered with vegetation.
Protecting the environment
One of the biggest things that protects the environment is boardwalks as they protect plants and animals from being stepped on or injured (at Cape Schnack and Gunnamatta). There is also chicken wire that stops people from getting under the railing or animals to get onto the plant, this can also stop animals from getting over (at Cape Schanck)
At all locations there is a variety of educational signs, telling you about wildlife which is very important as it can tell people about endangered wildlife(at all locations). The other educational information source is the signs about rips and other dangers at the beach which can cause harm(at Gunnamatta and St. Andrews).
Restricting Human Movement
A major contributor to constricting human movement is the fences which stop people from jumping of the boardwalk and walking around on the ground(at Cape Schnack and Gunnamatta). Also the paths already available are enough for people to easily get to and from the beachs meaning they don't need to run through the push, and sometimes large surrounding bushes block them(at Cape Schnack and Gunnamatta)
Restoring the environment
On some dunes there are gaps where plants have died, here there have been some new plants being planted on the dunes to try and stop the dunes from weathering(at all locations). They also planted some thicker bushes around the paths so that people couldn't go off the track, and they also have keep off signs and fences(at all locations)
