Because the velocity of the river slows down a great deal when it reaches the large body of water, the sediment that the river was carrying is deposited along the mouth of the large body of water.
Streams deposit most of the sediment they are carrying when they reach a body of water because the velocity of water slow down.
<h3>What is a stream?</h3>
It should be noted that a stream means a body of water that flows with the bed and banks of the channel.
In this case, due to the fact that the velocity of water slow down, the streams deposit most of the sediment they are carrying when they reach a body of water.
Well it depends on where you live but I would say that it would depend on the number of cars used by each families, the rate in which they use them. You can also mention the use of public transport as a method to reduce this pollution problems. Maybe include some statistics if you can find them. Use your daily life experience I think it could help you :)
