This expels the base of the cliff. CIE A Level Geography Abrasion: Pieces of rock and sand in waves are thrown against the cliff face. Tides are brought about by the gravitational draw of the moon and, to a lesser degree, the sun. Rotational slump is a type of mass movement that occurs in coastal environments.

Water quality and pollution management in the UK. /}0*gHtJTWzmg>ym How do joints influence cliff profiles and rates of erosion? For example: If less resistant, weak rock is at the base of the cliff, undercutting and collapse may occur. Human activities have a variety of complex effects on coastal erosion but most commonly the activities increase the strength of waves. 2 Rocks such as clay become saturated with water. If you looked down on a coastline from above and saw the geology of the area, youd be able to see that the rock type changes as you approach the coastline and that the different rocks are arranged in bands. Constructive waves are associated with weak discharge and strong swash, which develops deep-level shorelines, and are therefore more associated with coastlines of deposition. Sub-aerial processes include weathering and mass movement. What factors influence cliff profiles and rates of erosion? The significance of food, water and energy, An overview of global inequalities in the supply and consumption of resources, Carbon footprints, food miles and moves towards local sourcing of food. The neap tide delivers a low tidal range, in that the higher tide is lower than usual and the low tide more elevated. The video below shows a geo at Selwicks Bay, Flamborough. The cliffs vary in height, steepness and shape according to the geology of the area. Bays and headlands along a discordant coastline. Over time cliffs retreat due to a combination of sub-aerial weathering and coastal erosion.

The y-axis is often exaggerated on a beach profile. What two geology characteristics are dominant in influencing cliff profiles? The added weight of the saturated material, combined with the destabilization of the base, causes the slope to slump or rotate downward. Both rock type and structure can have a significant impact on coastal landforms. A cliff with landward dipping bedding planes.
