>> Coastline
Answer: Where the land meets the sea.
>> Fetch
Answer: The distance that a wave travels in open water.
>> Prevailing wind
Answer: The most frequent, or common, wind direction
>> Constructive waves
Answer: Waves with a strong swash and weak backwash which contributes
deposition to a beach.
>> Destructive waves
Answer: Waves with a strong backwash and weak swash which erodes a
coast.
>> Swash
Answer: The forward movement of a wave and material up a beach (can be
at an angle - depending on wind direction).
>> Backwash
Answer: The backward movement of water and material down a beach
when a wave has broken (at a 90 degree angle to the beach).
, >> Longshore drift
Answer: The zig-zag movement of sediment along a stretch of coastline
caused by waves approaching the beach at an angle.
>> Attrition
Answer: The process of erosion where transported particles hit against each
other making the particles smaller and more rounded.
>> Hydraulic Action
Answer: The process whereby rocks are eroded by the force of water in the
sea. Air trapped in cracks by the force of water can widen cracks causing
sections of cliff to break away from the cliff face.
>> Abrasion / Corrasion
Answer: A process of erosion which occurs when a wave hits the coast and
throws pebbles against the cliff face. These knock off small parts of the cliff
causing undercutting.
>> Solution / Corrosion
Answer: The process by which water (river or sea) reacts chemically with
soluble minerals in rocks and dissolves them.
>> wave cut platform
Answer: A flat, rocky platform found at the base of cliffs - produced by the
retreat of a cliff due to erosion. Usually seen at low tide. (Erosion landform)
>> Headland
Answer: A section of more resistant (harder) rock that sticks out into the sea
(e.g. igneous/metamorphic) (Erosion landform)
