transportation and deposition Flashcards
define traction
large sediment rolls along the sea bed as it’s pushed by sea currents
define saltation
smaller sediment bounces along the sea bed being pushed by currents, sediment is too heavy to be picked up by the flow of the water
define suspension
small sediment is carried within the flow of the water
define solution
dissolved material is carried within the water
where is the waves energy dissipated in headlands and bays
at the headland
define corrosion
where water in waves dissolves rock minerals
define abrasion
rocks carried by the sea are picked up by strong waves and thrown against the coastline causing more material to be broken off and carried away by the sea
define hydraulic action
the sheer power of the waves as they smash against the cliff, air becomes trapped in the cracks in the rock and causes the rock to break apart
define attrition
when rocks that the sea is carrying knock against each other
define wave quarrying
when high energy, tall waves hit the cliff face they have the power to enlarge joints and remove large chunks of rock in one go through vibration
