Weathering?
Is the breakdown of rocks where they are.
1 of 26
Erosion?
when the rocks are broken down and carried away by something.
2 of 26
Mass Movement
When the material shifts down as one.
3 of 26
Hydraulic Power?
waves crash against rock and compress the air in the cracks. this puts pressure on the rock, so it widens the crack and bits of rock fall off.
4 of 26
Abrasion?
eroded particles in the water scrape and rub against rock,removing small pieces.
5 of 26
Attrition?
eroded particles in the water smash into each other and break into smaller pieces. their edge also get rounded off as they rub together.
6 of 26
Corrosion?
Acids in seawater dissolve rock,chalk & limestone.
7 of 26
Backwash
the movement of the water back down the beach.
8 of 26
swash?
the movement of water up the beach.
9 of 26
Long shore drift
material is transproted along the coast.
10 of 26
Traction
large particles like boulders are puched along the sea bed by the force of water.
11 of 26
suspension
small particles like silt/clay are carried along in water.
12 of 26
saltation?
pebble sized particles are bounced along the sea bed by the force of water.
13 of 26
solution
souble materials dissolve in the water and are carried along.
14 of 26
deposition
when materials being carried away by ea water is dropped on the coast.
15 of 26
Spits
are beaches that stick out into the sea they are joined to the coast at one end.

Location of Holderness coastline
the holderness coast lies on the eastern side of UK, south of carborough facing the north sea.
17 of 26
Hard engineering
man made structions built to control the flow of the sea and reduce flooding and erosion.
18 of 26
Soft engeneering
schemes set up using knowledge of the sea and its processes to reduce the effects of flodding and erosion.
19 of 26
Arch
an archway formed where a cave has been eroded right through a headland.
20 of 26
stump
a rocky outcrop covered at high tide, its the eroded remains of a stack.
21 of 26
stack
an isolated pillar of rock formed when the roof of an arch falls.
22 of 26
sea cave
a hollow in a cliff face formed by the sea eroding a point of weakness in the rock.
23 of 26
cliff
a steep high rock face on the coast, formed where a ridge of high ground meets the sea.
24 of 26
wave cut platform
a gently sloping platform of rock at the base of a cliff, running out to sea. it marks the earllier position of the cliff and is covered in high tide.
25 of 26
cliff fall
a vertical crack in a rock. joints in a cliff are often the target for erosion by the sea.
