Step-by-step explanation:
Floods can drastically change the land in an area due to what is known as erosion. Erosion is the process of water carrying away small pieces of rock and soil. Over time, this can lead to large changes in the landscape. Floods can also deposit sediment, which can change the land in a different way. Deposition is the process of sediment being left behind by water. This can cause the land to become higher in some areas and lower in others.
