It is about 300 meters on average
The Amazon is actually the largest river, not longest. The Nile River actually is the longest river. The Amazon is wider, while the Nile is longer.
The nile isn't exactly the best river but it is wider and has more water than the amazon river but the amazon river is yet longer. hope it helped =D

A stream that is longer and wider is usually considered a BROOK or a RIVER.
It is called a river
The river delta.
Please rephrase - the question is unclear.
The Amazon River is the largest river in the world by volume, and it can get exceptionally wide during the heavy rains of the monsoon season. During this time of year, the Amazon River can reach up to 30 kilometers (19 miles) wide in some areas. This is because the monsoon season brings heavy rainfall, causing the water level to rise and the river to expand. This can be especially true in the lower reaches of the river, where the river's basin is much wider than in the upper reaches. The Amazon River's width can also vary depending on the location. In the central and upper reaches of the river (in Peru, Ecuador, and Colombia), the river is much narrower, typically ranging from 1 to 10 kilometers (0.6 to 6.2 miles) in width. In the lower reaches of the river (in Brazil), the river can be up to 30 kilometers (19 miles) wide. The amount of rainfall also plays a large role in how wide the Amazon River can get during the monsoon season. Generally, the more rainfall that occurs, the wider the river will become. For example, in the rainy season of 2009, the Amazon River reached its widest width in the past 100 years, expanding to an incredible 60 kilometers (37 miles) wide in some areas. The Amazon River is a constantly changing and dynamic river, and its width can vary greatly depending on the season, location, and amount of rainfall. During the monsoon season, the Amazon River can get exceptionally wide, reaching up to 30 kilometers (19 miles) wide in some areas.
A mature river
The Mississippi River is wider than the Columbia River. The Mississippi River varies in width along its course, but at its widest point near Alton, Illinois, it can reach over 3 miles wide. In comparison, the Columbia River is typically less than a mile wide.
rain takes away the dirt on the side of the river along with the current of water
