Lagoon
is a shallow
body of water separated from the ocean by barrier islands or coral reef.
Long shore drift is the zigzag movement of sediment along the beach by waves approaching the shore at an angle. The swash transports sediment up the beach at an angle and the backwash drags them at right angle to the beach.
Long shore bar is a ridge of sand deposited in the offshore zone by the strong backwash of destructive waves.
Low water mark
indicates the limit of beach material that is always submerged.
Mass movement is the downward movement of all weathered material.
Notch is a hollow between the high and low water mark. This forms by the undercutting of cliffs due to wave action.
Overhang
is the upper
part of cliff jutting out over a notch.
Pebbled
beach is a
type of beach, characterized by a steep gradient and selective distribution of
pebbles: the smallest are found
near the shore and the largest are found further inland.
Raised
beach is an
ancient beach now found above the present sea level due to an uplift of the
land.
Ria coastline is a drowned river valley. It is deepest at its mouth and becomes progressively shallower inland.
