Erosion is....

• ...when sediment is transported

• ...when sediment is dropped

• ...when sediment is broken apart

Hydraulic action is an example of....

• Erosion

• Deposition

• Transportation

Traction is an example of...

• Erosion

• Transportation

• Deposition

Material is deposited when...

• The load is too big to carry

• The river loses its energy

• The river meets the sea

• All of the above

Saltation is where...

• Rocks are rolled along the river bed

• Rocks are carried along in the water

• Rocks are 'hopped' along the river bed

The force of the water hitting the river bed and breaking it apart is...

• abrasion

• solution

• hydraulic action

• traction

Solution is where...

• rocks carried by the water wear away the river bed

• rocks are dissolved by the river

• rocks knock against each other and break apart

What jobs does a river do?
