Processes Of Erosion Flashcards
1
Q
What is hydraulic action?
A
force of water against bed and banks
2
Q
What is abrasion/corrasion?
A
Bed and banks are worn down by rivers load
River throws these particles against bed and banks
3

A
Material carried by river bump into each other and are smoothed and broken down into smaller particles
4
Q
What is corrosion?
A
Chemical action of river water; acids in water slowly dissolve bed and banks
