they deposit their load because otherwise it gets too heavy
The speed the water is traveling is greatly reduced where the river spreads out and the soil has a chance to drop out.
Because the heaviest stuff is the first to settle to the bottom. Heavier stuff sinks fastest.
It drops the material. This is called deposition :)
The heaviest sediment will always be deposited first. Which sediment is the heaviest in that flowage can vary widely.
I believe that is from BC Science 7 and the answer is a delta.
This deposit is called a "delta".
The end of the river. Known as the mouth of the river.
a place where a river meets the shore
The river drops the heaviest material first.
They deposit them later as the go along. At the end of the river the left over material forms a delta.
accumulated sediments on the bottom of the river
A deposit at the opening of a river is called delta.
A deposit at the mouth of a river is called a delta. This land form is created because of the deposition of sediments carried by a river as the flow leaves its mouth.
the nile delta is a fan-shaped mud deposit at the mouth of the nile river
