Flashcards in Erosion, Transportation And Deposition Deck (14):
How many erosion processes are there?
Force of water breaks rock particles away from river channel
Eroded rocks picked up by river scrape and rub against channel, wearing it away
Eroded rocks picked up by river smash into each other, break into smaller bits. Edges get rounded off as they rub together
River water dissolves some types of rock
The movement of eroded material
What are the 4 processes of transportation?
Traction, saltation, suspension and solution
What is traction?
Large particles (boulders) pushed along river bed by water
What is saltation?
Pebble-sized particles are bounced along river bed by water
What is suspension?
Small particles are carried along by water
What is solution?
Soluble materials dissolved in water and are carried along
When a river drops eroded material
When deposition occur?
When a river slows down (loses velocity)
