The five main processes in which river erosion occurs Hydraulic action - the pressure of the water breaks rock and soil particles away from the river bed and bank.Hydraulic action is strongest where water movement is most intense such as at waterfalls, and during floods. Mass movement is the downslope movement of material (rock and soil) under the force of gravity. 2B.8A - Human Activity and Coastal Recession. Currents are basically of two types in geography:- 1. Wind transports sand in 3 ways. . Oxbow lakes usually form in flat, low-lying plains close to where the river empties into another body of water. Open questions begin with such as: what, why, how, describe. What problems are caused by global warming? Posted by Unknown at 09:51. clay). What are active, dormant and extinct volcanoes? How have animals adapted to cold environments? It is the most widespread, slow, down-hill movement of regolith and soil under the influence of gravity. Permafrost can be found on land and below the ocean floor. Erosion is the process that wears away the river bed and banks. How reliable are economic indicators of development? What is the internet? There are four types of erosion: Hydraulic action - this is the sheer power of the waves as they smash against the cliff. The weight of the saturated clay causes the material to slump along the slip plane. If the rock layers are horizontal, small overhangs of more resistant rock form in the cliff face.

Where there is limited vegetation to bind the soil together and the ground is very saturated heavy rain can produce sheet flow over the upper cliff surface. what is slumping in geography bbc bitesizecabarrus county abc lottery what is slumping in geography bbc bitesize Coastal landforms are created through processes such as erosion and deposition. How did the temperate deciduous woodland get like this? The general re-shaping of the land by normal atmospheric processes, for example wind and rain; includes weathering, mass movement, erosion and deposition. Mass movement.
