Why is the streambank on the outside of this meander steeper than the streambank on the inside of this meander?

• slower water causing erosion

• faster water causing deposition

• slower water causing deposition

The image below shows a point bar and a cut-bank of a meander. What happens to sediments at these locations?

• Sediments are deposited on a point bar and on a cut-bank.

• Sediments are eroded from a point bar and from a cut-bank.
