What are the 4 types of erosional processes?
What are the 4 types of erosional processes?
There are four main processes of erosion along the coast. These are hydraulic action, abrasion and corrasion, attrition and solution.
What are the 3 erosional processes of rivers?
Rainfall and surface runoff Splash erosion is generally seen as the first and least severe stage in the soil erosion process, which is followed by sheet erosion, then rill erosion and finally gully erosion (the most severe of the four).
How does a river erode GCSE?
The four main forms of river erosion The pressure weakens the banks and gradually wears it away. Abrasion – rocks carried along by the river wear down the river bed and banks. Attrition – rocks being carried by the river smash together and break into smaller, smoother and rounder particles.
What are the three river processes?
River processes
- Erosion – the wearing away of the land and the stones carried in the river.
- Transport – the movement of rocks, sand, and silt by the river.
- Deposition – the dumping of rocks, sand and silt wherever the river slows down.
What is erosion BBC Bitesize?
Erosion is the wearing away of rock along the coastline. Air becomes trapped in the cracks in the rock and causes the rock to break apart. Abrasion – this is when pebbles grind along a rock platform, much like sandpaper.
What are the 3 main types of erosion?
Erosion involved three processes: detachment (from the ground), transportation (via water or wind), and deposition. The deposition is often in places we don’t want the soil such as streams, lakes, reservoirs, or deltas.
What are 3 types of erosion?
The main forms of erosion are: surface erosion. fluvial erosion. mass-movement erosion.
What are the erosional processes?
Erosional processes along coastlines include: (1) the direct effects of hydraulic action, wedging, and cavitation by waves; (2) abrasion (corrasion), using sand, gravel, and larger rock fragments as tools; (3) attrition of the rock particles themselves during this abrasive action; (4) salt weathering or fretting; (5) …
What is erosion in a river ks2?
Erosion is the process that wears away the river bed and banks. Abrasion – When pebbles grind along the river bank and bed in a sand-papering effect. Attrition – When rocks that the river is carrying knock against each other. They break apart to become smaller and more rounded.
What are erosional processes?
What are the main processes of erosion?
Destructive waves erode through four main processes; Hydraulic Action, Compression, Abrasion and Attrition.
What are the 6 types of erosion?
6 Types of Soil Erosion
- Sheet Erosion. If rainwater begins to move the soil that’s been loosened by splash erosion, the erosion of the soil progresses to a new stage.
- Rill Erosion.
- Gully Erosion.
- Wind Erosion.
- Floodplain Erosion.

How are the processes of erosion and mass movement related?
Coastal processes. Processes called erosion, mass movement and weathering break down and remove material from the coast. The material is moved along the coastline by the sea and deposited when there is energy loss. Erosion. Erosion is the wearing away of rock along the coastline. Destructive waves are responsible for erosion on the coastline.
How is erosion related to transportation and deposition?
Erosion, transportation and deposition all occur in a river. Moving from the upper course to the lower course, the rates of erosion, transportation and deposition change. Erosion. Erosion is the process that wears away the river bed and banks.
What kind of erosion occurs in the UK?
Solution – this is when sea water dissolves certain types of rocks. In the UK, chalk and limestone cliffs are prone to this type of erosion. 1 2
How does erosion take place in a river?
Erosion is the process that wears away the river bed and banks. Erosion also breaks up the rocks that are carried by the river. Hydraulic action – This is the sheer power of the water as it smashes against the river banks. Air becomes trapped in the cracks of the river bank and bed, and causes the rock to break apart.
