True
This is impossible to answer due to the issue of hydrodynamics. Rapids are constantly being gained and lost due to the action of the water's movement (erosion). Also, the rainy season would cause some of the smaller rapids to be covered.

If you mean how the river widens, the usually cause is erosion.
An unusually rainy period can cause rivers to overflow their banks and flood the areas surrounding them. The erosion, caused by rivers, can happen very quick.
Yes, valleys can cause erosion. The flow of water through valleys can carve out the land, carrying away soil and rock particles. Additionally, glaciers moving through valleys can also contribute to erosion by grinding and transporting material.
They Create Deltas.
Erosion of the river banks altering the course; deposition of gravel, sand and mud in calmer stretches; obstructing of the river mouth with sand-bars forming in the estuary and inshore.
Weathering and erosion weaken the outer banks of a river, causing them to erode more quickly than the inner banks. This leads to a gradual sideways shift in the direction of the river flow, creating meanders. Over time, the continued erosion and deposition processes along the bends of the river further accentuate its meandering shape.
how does a person cause a soil erosion
No, tornadoes do not cause deposition. Tornadoes are mainly associated with erosion, as they can pick up and carry loose particles and debris within their strong winds. Deposition usually occurs when the wind slows down and drops these materials.
There are several things that cause erosion, and acid rain is one of them.
