What are the three ways in which a river erodes its valley?
Corrasion, Hydraulic action, Attrition
What is the difference between hydraulic action and abrasion?
By: Gwen The difference between abrasion and hydraulic action is that: In "Hydraulic action" the water flows so fast that it is forced to crack the bank BUT For in "Abrasion" the river bed is broken/cracked because of the rock and stones in the river.
What are three types of erosion that can affect a river valley?
Three types of erosion that can affect a river valley are hydraulic action, abrasion, and attrition. Hydraulic action refers to the force of moving water eroding the river banks, abrasion is the process of rocks and sediment in the water wearing away the riverbed, and attrition occurs when rocks in the river collide, break down, and become smoother over time.
Do river turn wider when it goes to the downstream?
Yes it does, one of the reasons is erosion. Hydraulic action and corrosion erode the bends of the river making the outside bend wider. :P
What are the three ways of river erosion?
The three ways of river erosion are hydraulic action (force of water on the river banks), abrasion (wearing down of the riverbed by sediment), and attrition (erosion caused by rocks and sediment carried by the river rubbing against each other).
What are two processes of erosion found in rivers?
The two erosional processes found in rivers are mainly attrition and vertical hydraulic action. Attrition is where the moving river water dislodges materials like rocks on the sides of the river and carries them with the flow. Vertical hydraulic action is where moving water removes materials from the riverbed and carry it with the flow. This causes less resistant rocks to be eroded and thus forming a plunge pool, or waterfall.
What type of erosion accours on the outside bend of a river?
Lateral erosion, also known as undercutting, occurs on the outside bend of a river. This is where the force of the water is strongest, causing the river to erode the outer bank through hydraulic action and abrasion.
What is A feature of coastal erosion by hydraulic action?
Hydraulic action is a process in which the water is forced to go in the cracks of stone and with the passage of time it breaks down so when this action appears it destroys the bank or the coast.This is the feature of coastal erosion by hydraulic action.MARIAKHALID

Are bicycle brakes considered as hydraulic action?
depends on the type. There are hydraulic bike brakes, but most are mechanical.
Why is there sand at the bottom of many river beds?
The abrasion and attrition combined with hydraulic action on the river bed and the river banks erode away the underlying rock which results in small grains of rock we call sand. Depending on the speed of the river and the size of the particles, the sand will be deposited by the river at different stages (usually though it is found near the mouth of the river).

Measure of a river's channel efficiency (its ability to move water and sediment)
