By Glaciation & Rivers 2 of 38 Highest peak UK Ben Nevis, Grampian Mountains, Scotland 3 of 38 Highest Peak England Scarfell Pike, Lake District 4 of 38 Highest Peak Wales Snowdon, Cambrian Mountains 5 of 38 Lowest UK point The Fens, East Anglia 6 of 38 Longest River River Severn 7 of 38 Fetch Distance wind travels over surface of water 8 of 38 Swash Water that runs up the beach after the wave breaks 9 of 38 Backwash Water runs down to sea after wave breaks 10 of 38 Constructive Wave Low wave with strong swash deposits sediment creating gently sloping beach 11 of 38 Destructive Wave High wave with strong Backwash removes sediment creating a steep beach 12 of 38 Erosion Mechanical wearing away of rocks (along the coast) 13 of 38 Weathering Breakdown of rocks in situ (one place) 14 of 38 Types of Weathering Mechanical (physical), Chemical and Biological 15 of 38 Mechanical weathering (definition + example) Disintegration of rock - Freeze-Thaw 16 of 38 Chemical weathering (definition + example) Caused by chemical changes - Carbonation 17 of 38 Biological weathering (definition + example) Caused by the Flora and fauna - plants growing in cracks/ animals burrowing into weak rocks 18 of 38 Mass movement downward movement of weathered rock due to gravity 19 of 38 Rockfall Bits of rock break away due to freeze thaw 20 of 38 Mud flow saturated soil and weak rocks flow downhill 21 of 38 landslide blocks of rocks slide downhill 22 of 38 Rotational slip Saturated soil slumps down on a curved surface 23 of 38 Type of wave responsible for erosion Destructive Waves 24 of 38 Hydraulic Action Force of wave traps air which gets forced into cracks in rock and over time breaks up rock 25 of 38 Abrasion Rocks grind over rock platform, like sandpaper, become smooth 26 of 38 Attrition Fragment of rocks carried by the sea knock against each other and become smaller and rounder 27 of 38 solution Sea water dissolves certain types of Rocks (Chalk, Limestone) 28 of 38 corrasion Rock fragments carried by the sea scrape away at the cliff 29 of 38 Deposition Happens when water slows down and waves loose energy 30 of 38 What is formed because of deposition Beaches due to sediment deposition and Mudflats and salt marshes in sheltered areas behind spits. 31 of 38 name ways sediment is transported Solution, Suspension, Traction and Saltation. 32 of 38 Solution Dissolved chemicals in water (from Chalk/Limestone) 33 of 38 Suspension Particle are suspended/carried in the water 34 of 38 Traction lage pebbles rolled along the seabed 35 of 38 Saltation Bouncing of particles at the bottom of sea as they're too heavy o be suspended. 36 of 38 Prevailing wind The usual direction of wind 37 of 38 Longshore drift Process of sediment being transported along the coast in a zig-zag movement due to the angle of prevailing wind 38 of 38
