Since the Mississippi flows into the ocean and carries all that mud with it, why is the river getting deeper or wider over time eventually disappearing? Also where does its water come from?
In: 1
Rivers do get deeper over time.
The Grand Canyon is the result of thousands of years of the Colorado river digging down into the ground.
As to where the water comes from, that’s called a ‘watershed’ and it’s usually rain over a large area that drains down into the river, or snow that melts and flows down the mountains into a river.
