Question		Answer
Abrasion start learning		A type of erosion caused by waves picking up sediment and rubbing them against cliffs.
Attrition start learning		A type of erosion where sediment carried by waves is worn down as they collide with each other, so they become smaller more rounded.
Bars start learning		A ridge of sand or shingle across the entrance of a bay.
Beach nourishment start learning		Also known as recharge, when sand or shingle is added to a beach to make it higher or wider.
Concordant coastline start learning		When a rock type runs parallel to the coastline.
Discordant start learning		Where bands of hard and soft rock lie at right angles to the coastline forming headlands and bays.
Erosion start learning		The action of water wearing away rocks. There are four key erosion processes – hydraulic action, abrasion, solution and attrition.
Fault start learning		A fracture or break in rocks caused by tectonic activity.
Hydraulic action start learning		The sheer force of waves wearing away sea cliffs.
Joint start learning		A vertical crack within a layer of rock formed as rock cools during the metamorphic process.
Longshore drift start learning		The movement of material along the beach transported by wave action.
Managed retreat (realignment) start learning		Allowing the shoreline to change naturally but manage and direct the process.
Mass movement start learning		The movement of material down a slope due to gravity e.g. sliding.
Prevailing wind start learning		Direction in which the wind blows from most frequently
Saltation start learning		A process where sediment is transported by repeatedly being picked up and dropped as wave energy fluctuates
Seasonality start learning		Annual recurring periods during the year or specific periods when events occur e.g. coastal flooding.
Sliding start learning		Where material moves rapidly downslope in one go e.g. a landslide.
Slumping start learning		When material moves downslope in a rotational manner along a curved surface.
Solution (erosion) start learning		Slightly acidic/salty water can dissolve some rocks e.g. chalk.
Solution (transport) start learning		Dissolved sediment in the sea is moved by wave action.
Storm frequency start learning		The number of storms that occur in a given period of time.
Suspension start learning		Smaller sediment particles are carried within the wave action.
Traction start learning		Larger sediment is rolled along the sea bed.
Wave-cut platform start learning		A flat area of rock at the bottom of cliffs seen at low tide.
Weathering start learning		The breakdown and decay of rock by natural processes acting on rocks.
