erosion of cliffs provides direct input (abrasion , quarrying hydraulic action) // currents bring material from the sea bed (constructive waves) // rivers bring sediment downstream (saltation suspension)
1 of 9
what happens to the sediment in a sediment cell
stored as a depositional landform e.g. bar or spit // stored as a near shore feature e.g sand dune // transported as a throughput and becomes an output (LSD) // transported put to sea (destructive waves)
2 of 9
types of sediment
classic sediment = from rocks and weathering // biogenic sediment = shells and skeletons of marine organisms
3 of 9
what is the main agent of transportation and deposition
waves (constructive and destructive) // winds (LSD) // tides
4 of 9
what is a cusp
formed when there is a junction of sand and shingle , they are semi circular depressions formed by a collection of waves meeting the same point
5 of 9
what is a berm
found under storm ridges that marks the successively lower high tide mark as the cycle goes from spring to neap tide. formed when material is moved up he beach with incoming tides
6 of 9
what is a cuspate foreland
when the beach material is exposed to LSD in opposing directions
7 of 9
what is a tombolo
where ridges of sand and shingle link the coast to an island
8 of 9
what are ridges and runnels
run parallel to the shore line , the spreading out of the waves energy across a wide area of beach common on shallow sandy beaches
