What are the 4 processes of erosion?

Destructive waves erode through four main processes; Hydraulic Action, Compression, Abrasion and Attrition.

Is Corrasion and attrition the same?

The four types of river erosion Abrasion/Corrasion – the force of the water in the river carrying stones and other materials grinds the bedload like a piece of sandpaper. Attrition – rocks being carried by the river smash together and break into smaller, smoother and rounder particles.

How Corrasion abrasion erodes the cliffs?

Abrasion, also known as corrasion, occurs when waves break on cliff faces and slowly erode it. As the sea pounds cliff faces it also uses the scree from other wave actions to batter and break off pieces of rock from higher up the cliff face which can be used for this same wave action and attrition.

What are the 2 main processes of erosion?

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 are the 2 types of erosion?

There are two types of erosion: intrinsic and extrinsic.

What happens during attrition?

Attrition occurs when the workforce dwindles at a company, following a period in which a number of people retire or resign, and are not replaced. A reduction in staff due to attrition is often called a hiring freeze and is seen as a less disruptive way to trim the workforce and reduce payroll than layoffs.

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.
