||||
| Sediment | show 🗑
|
||||
| show | The river cuts down like a saw this is called downward erosion.Raining in the V-Shaped valley will make it wider
🗑
|
||||
| Waterfall | show 🗑
|
||||
| show | Water on the outer curve is fast and water on the inside is slow.Erosion takes place on the fast.Deposistion takes place on the slow.Over time the erosion increase and so dors the deposistion.A meander is formed.
🗑
|
||||
| show | During a flood the river cuts across the meander.After time deposistion builds up along the edge and the oxbow lake is closed off the water stays the same.
🗑
