Quiz 2
Aeolian – Characterized by a sighing or moaning sound as if produced by the wind.
Spinifex – genus of perennial coastal grasses. They are one of the most common plants that grow in sand dunes along the coasts
Constructive waves – a low height, low frequency wave where the net movement of material is up the beach as the swash is stronger than the backwash.
Corrasion – The wave action moves rock and other material across the rock shelf and wears away the rock in an abrasive fashion.
Corrosion – In rocks along the coast there are minerals like iron. When waves break they wet the rocks. As the rock dries the salt in the sea water crystallises and acts on the minerals in the rock to erode material.
Refraction – When waves bend due to headlands and the contours of the ocean floor
Deposition – process by which material is added to a landform or land mass.
Destructive waves – found on steep beaches, are steeply breaking and mainly responsible for coastal erosion. Their backwash is much stronger than their swash.
Erosion – The process of eroding or being eroded by wind, water, or other natural agents
Hydraulic action – form of erosion caused by the force of moving water currents rushing into a crack in the rockface.
Longshore drift – The movement of material along a coast by waves that approach at an angle to the shore but recede directly away from it
