Large boulders and smaller rocks can be carried by a river. When rocks and sediment are displaced, it's called erosion.
A river channel is formed by rock and soil of a stream being transported down, during this process the channels become wider and deeper.
Because the pieces of rock are eroded a it passes down to the bottom of the river.

Igneous rock is transported by wind or moving water until they are deposited in other regions where they settle in layers.

This process is called erosion. Erosion occurs when running water, like a river, picks up and carries away rock particles, eventually depositing them in another location.
