Sea Flashcards
Hydraulic action
the force of the water on the cliffs or coastal rocks. The force of water has the power to break the rocks apart.
Abrasion
when rocks and pebbles flung by waves wear the coastal rocks away.
Attrition
when eroded rock particles are worn down, becoming smaller and rounded.
Corrosion
the process whereby certain rocks and minerals such as chalk and limestone are dissolved in water.
Erosion by wave action is primarily caused by?
hydraulic action,
corrasion (or abrasion),
attrition and
corrosion.
A cliff
a very steep overlooking rock.
A headland
a narrow piece of land that projects from a coastline into the sea.
A bay
an area of ocean, sea, or lake enclosed by land but with a wide mouth that allows access to the sea.
A sea cave
a hollow opening in the base of the sea cliff formed by waves acting on weak parts of the rock.
An arch
the natural bridge formed where a cliff is subjected to erosion by the sea
A stack
an isolated pillar of rock that has been separated from a headland by coastal erosion. It is formed by the collapse of an arch.
