Erosion:

* Outside Bend (Cut Bank): The fastest-flowing water is on the outside of the bend. This faster water has more energy, causing it to erode the riverbank, creating a steep, concave bank known as a cut bank.

Deposition:

* Inside Bend (Point Bar): The water slows down on the inside of the bend. This slower water loses energy and deposits sediment, creating a gentle, convex bank known as a point bar.

Here's a visual breakdown:

* Imagine a river flowing in a curve: The water on the outside of the curve is moving much faster than on the inside.

* Fast water = Erosion: The fast water has the power to pick up and carry sediment, eroding the bank.

* Slow water = Deposition: The slow water loses its energy and drops the sediment, creating the point bar.

The Process:

1. Fast-flowing water on the outside bend erodes the riverbank.

2. Sediment is picked up by the water and carried downstream.

3. Water slows down on the inside bend.

4. Sediment is deposited on the inside bend, building up the point bar.

Over time, this process of erosion and deposition can cause a river to meander significantly, changing its course and creating new landscapes.
