Lateral erosion is one of the three different ways that rivers and streams erode their banks and beds. As the term implies, lateral erosion is the erosion that occurs on the sides, or floodplains, of a river or stream, and it is also referred to as bank erosion. The other two forms of erosion are headward erosion and downcutting erosion Learn about and revise river landforms, whether created through erosion or deposition, with GCSE Bitesize Geography (AQA) GCSE Geography Revision Pack: granite is far more resistant to erosion than soft rocks, such as clay).

Lateral Erosion If you take a look at a cross profile diagram of a river, then it is easy to see that rivers widen at certain points. They usually start off narrow in the upper course, so a wide river tells us that we are looking at either the middle course or the lower course GCSE Rivers Glossary. Abrasion: the pebbles being transported wear away the bed and banks of the river channel. Alluvium: rock particles (clay, silt, sand and gravel) deposited by a river. Attrition: The particles are knocked about as they are transported, and they gradually become more rounded and reduced in size.. Base Level: the mouth of the river and the point where the gradient becomes zero In the lower course, the rapid lateral erosion cuts into the neck of the meander, narrowing it considerably. Eventually, the force of the river breaks through the neck, and as this is the easiest way for the water to go, the old meander is left without any significant amount of water flowing through it GCSE Glaciated Valleys Glossary. Abrasion: erosion caused by rocks and boulders in the base of the glacier acting like a giant file scratching and scraping the rocks below. Angular Rock: a rock with sharp edges. Arête: sharp, knife-like ridge formed between two cirques cutting back. Aspect: the direction a cirque faces; south-facing cirques tend to be larger and more eroded due to greater ice.

Lateral erosion - Sideways erosion by a river on the outside of a meander channel. It eventually leads to the widening of the valley and contributes to the formation of the flood plain. Long profile - The gradient of a river, from its source to its mouth. Vertical erosion - Downward erosion of a river bed Ox Bow lakes: Continual erosion on the outside bends, results in the neck of the meander getting narrower until the river undercuts through the neck and shortens the coarse.The current will take the path of least resistance, giving it renewed energy. The faster current will now be flowing in the centre of the channel and deposition is more likely next to the banks GCSE Geography A - Paper 1 Mark scheme 1GA0/01 Que stion number An wer Mark 1 (a) (i) B Granite The correct answer is granite as this is the only example of an igneous rock listed.

These are generally depositional in nature and are brought by both continental ice sheets and glaciers. The later leaves behind the eroded materials in only restricted areas. The imprint of ice-sheets on the landscape is far more widespread because they advanced through the large areas during the Ice Ages. The gradient is more gentle and lateral (sideways) erosion has widened the channel. The river channel has also become deeper. Meanders and oxbow lakes are typical landforms found in this stage of the river

Lateral moraines form at the edges of the glacier as material drops onto the glacier from erosion of the valley walls.Medial moraines form where the lateral moraines of two tributary glaciers join together in the middle of a larger glacier. Sediment from underneath the glacier becomes a ground moraine after the glacier melts. Ground moraine contributes to the fertile.
Due to lateral erosion, the river widens and the river water flows over flatter land to develop larger bends which are referred to as 'meanders.' The characteristic sinusoidal (sinewave-like or snake-like) flow of water is therefore exhibited after the complete formation of meanders at the middle course of river bodies In areas where vertical erosion is dominant - waterfalls and gorges are commonly found In areas where lateral erosion and deposition become...

Aerial photograph: A photograph of an area of the earth's surface. 1) In the lower course of the river the gradient is gentler than in the upper course. The river has more energy and the volume amount of water is high. 2) In the lower course there is more lateral (sideways) erosion.The channel is wide and deep.The river has less friction to overcome which means that the river can flow faster. 3) As the river erodes sideways, it swings from side to side. A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or a rock layer moves a short distance down a slope. Movement is characterized by sliding along a concave-upward or planar surface. Slumps have several characteristic features BSL Geography Glossary - Plunge Pool - definition. Definition: What is a plunge pool? A plunge pool is found at the bottom of a waterfall and is formed by erosion. As water drops over the waterfall then hits the ground beneath, it causes erosion, which forms a pool.

A reduce in water will make the channel width narrower. This is because less (lateral) erosion will occur, in-order to deepen the channel. From sites 3 to 5, the channel gradually re-widens; rising significantly from 2.7m to 6.7m
Lateral erosion: This process increases a river's width. A large sediment load has to be entrained for this process to work most effectively. It is responsible in conjunction with the processes of slope transport and mass movement for valley widening, meander migration and river cliff formation Year 10 LC4 MTP - GCSE Geography King's Leadership Academy, Warrington - Students may confuse vertical and lateral erosion - Students get confused at how waterfalls create gorges over time - Students get confused about where the fastest flowing water is found on a meander (resulting in confusion over where erosion and deposition. erode sideways (lateral erosion) rather than downwards and the river begins to deposit sand and gravel.

These geological formations appeared by erosion over time. In the upper course of the river, vertical erosion is more dominant compared to lateral erosion. While flowing downhill quickly, rivers remove maximum sediments from the bottom floor of the river channel than from riversides. This process is known as downcutting Surface run-off and throughflow cause erosion at the point where the water enters the valley head. Vertical erosion makes a river channel deeper. This happens more in the upper stages of a river (the V of vertical erosion should help you remember the V-shaped valleys that are created in the upper stages). Lateral erosion makes a river wider Corrosion geography diagram Erosion - corrasion - GCSE Geography - BBC Bitesiz . An illustrated explanation of rivers - weathering, erosion and corrasion.
