Coastal Transportation and Depostion 0.0 / 5 ? GeographyCoastal zonesGCSEAQA Created by: nimrahali12Created on: 06-09-16 17:53 What does transportation mean? the movement of material 1 of 22 Material is transported along coasts by a process called? longshore drift 2 of 22 Waves follow the direction of? prevailing(most common) wind 3 of 22 They usually hit the coast at? oblique angle (not a right angle) 4 of 22 The swash carries and in what direction? material up the beach in the same direction of the waves 5 of 22 The backwash carries and what direction? carries material down the beach at right angles back towards the sea 6 of 22 What material is along the coast? zig zag material 7 of 22 What are the four process of erosion? traction,saltation,suspension and solution 8 of 22 What does traction mean? large particles like boulders are pushed along the sea bed by the force of water 9 of 22 What does Saltation mean? pebble sized particles are bounced along the sea bed by the force of water 10 of 22 What does suspension mean? small particles like silt and clay are carried along in the water 11 of 22 What does solution mean? soluable materials dissolve in the water and are carried along 12 of 22 What does deposition mean? dropping of material 13 of 22 When are coasts built up? when the amount pf deposition is greater than the amount of erosion 14 of 22 The amount pf material that deposited on an area of coast is increased when? There is lots of erosion elsewhere on the coast, so there is lots of material available and there is lots of transportation of material into the area 15 of 22 What do low energy (slow)waves do? carry material to the coast but they are not strong enough to take a lot of material away 16 of 22 This means? there is lots of deposition and very little erosion 17 of 22 Waves that deposit more material than they erode are called? contructive waves 18 of 22 What frequency is constructive waves? low (6-8 per min) 19 of 22 How do they look like? low and long 20 of 22 What does the swash look like? It is powerful and carries material up the coast 21 of 22 What does the backswash look like? It is weaker and it doesn't take up a lot of material back down the coast. This means the material is deposited on the coast 22 of 22
