Fetch
the distance travelled by wind or waves across open water.
Swash
A layer of water that washes up on the beach after an incoming wave
Backwash
After the swash the water runs back down the beach
Destructive waves
They occur when wave energy is high and the wave has travelled over a long fetch. They tend to erode the coast.
Constructive waves
wave that leads to the build-up of a beach
Wave cut platform
the narrow flat area often found at the base of a sea cliff or sea that was created by erosion.
Bedding planes
The surface that separates the layers of rock
Joints
A joint is a break (fracture) of natural origin in the continuity of either a layer or body of rock
Bays
A coastal body of water that directly connects to a larger main body of water, such as an ocean, a lake, or another bay.
Stump
Eventually, erosion will cause the stack to collapse, leaving a stump.
Headlands
DescriptionA headland is a coastal landform, a point of land usually high and often with a sheer drop
Wave cut notch
A wave-cut notch is formed by erosional processes such as abrasion and hydraulic action. As the notch increases in size, the cliff becomes unstable and
Cave
A natural void in the ground, caves often form by the weathering of rock
Arch
Natural bridge
Stack
Geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, formed by wave erosion
