River Processes

What are tributaries?

• bends in the river

• wide areas of water near the mouth

• where the river reaches the sea

• small streams or rivers that run into the main channel

Which one of these river processes is the movement of material that is dissolved in water?

• traction

• suspension

• saltation

• solution

Which one of these processes is the movement of material that is carried within the water flow?

• traction

• suspension

• saltation

• solution

Which one of these processes is the movement of particles 'leap frogging' along the river bed?

• traction

• suspension

• saltation

• solution

Which one of these processes is the rolling of stones along the river bed?

• solution

• saltation

• suspension

• traction

The sheer force of water and air forcing itself into the soil and moving away parts of the land and banks of the river is called....

• hydraulic action

• corrosion

• abrasion

• attrition

What happens when smaller material rubs against the bed and banks of the river?

• attrition

• corrosion

• abrasion

• hydraulic action

Attrition occurs when...

• particles of load collide and knock pieces off each other

• smaller material rubs against the bed and banks of the river

• acid in the water dissolves particles of rock from the bed and banks of the river

• the sheer force of the water and air forcing itself into the soil

What is carried downstream by a river?

• boulders

• rocks

• silt

• load

Some particles are eroded by being dissolved in the weak acids of water.

• Corrosion
• Abrasion
• Attrition
• Hydraulic Action
