A river flows from a region of higher elevation to a region of lower elevation and is structurally controlled. As it flows towards the sea or ocean body, the strength of the river decreases and carries a lesser amount of sediments along with it. These sediments are sometimes deposited in a large amount in such a way that the sea waves cannot erode, thereby resulting in the formation of layers of sediments, which are commonly known as delta. A delta is considered to be the mouth of the river.
Some wealthy Patricians and Plebeians families got together and made a new ruling class that took over the political officers and Rome never became a Democracy. Hope this helped please rate as brainliest thank!! :)
