The soil that can be found at the mouth of a river, or perhaps a creek (or any other water source, as a matter of fact), is extremely fertile. Fertile, yes, but also extremely wet. It is in fact absolutely impossible for plants to grow at the mouth of a water source, because the ground is too wet. Impossible, except for one complicated answer : the water frog. This specific type of amphibian can only be found in Brazil or in Peru (or rarely found in Equator and Venezuela). Its only purpose in life, other than reproducing, in sitting directly on a source of water and absorbing the chemical found in the water that disables plants to grow in water : asterion. The water frog absorbs asterion and then makes it leak out of its pores as a new chemical, called desasterion. This liquid does not make plants not grow in water, in fact, it enables them to grow.
If the river is moving slower than ~0.01 cm/sec, then clay may be found in the river bed. If it is slower than ~0.3 cm/sec, then silt may be found. Any faster and the clay and silt would be deposited at the mouth of the river where the velocity decreases greatly.
Fertile soil is a natural resource. If nobody had ant fertile soil... where would we be? We wouldn't be able to grow annything or be able to feed our live stock.
The area around the Nile River Delta had some of the world's most naturally fertile soil. Unfortunately, in recent years the Egyptian government has dammed the Nile river for electricity production, preventing the river from flooding and depositing humus on it's shores. When the Nile did flood and recede, the fertility index of the soil around went from around a 10 to a 13
rivers leave fertile soil along their banks after floods
Fertile soil was created in the Mesopotamia from the melted snow and rain that would flow down towards the land.
sedimentary
Because of the water it has. Also the water gives the soilmore nutrients
an example of a river mouth would be the mouth of the Mississippi river
A delta is the mouth of a river.
That would be the mouth of the Columbia River at Astoria, Oregon.
That Would Be The Hudson River
the Nile river would flood annually which made Egypt extremely fertile GO BEARS 3-0CHEESE MONKEYThe Nile River helped to make Egypt fertile by helping to produce fertile rich soil.
The Amazon River has its mouth at the Atlantic Ocean. The Amazon River The Amazon is the largest river in the world at about 4,000 miles / 6,500 km
As far as I know, A river's mouth is simply called the 'river mouth'!
Usually it would be an estuary.
This would be the Mississippi River .
The advantages there would have been to living near both the Arabian and Indus River would have been that there would have been fresh water for farming, bathing and drinking. There was also fertile land to farm on. There were also disadvantages which would have been that along the shorelines there would have been the Eastern Mountains, taking up space for multipul things.
