no.
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.
The Ohio River is the largest river in ohio. It runs the South and most of East border. It runs down Indiana and Kentucky then bumps into the Mississippi River and creates a tributary Tributary: 2 rivers that runs into each other
The Pacific Ocean is not 'long'; it is wide. But the Pacific is much wider [maximum 12,300 miles] than the Mississippi is long [2320 miles].
A mature river erodes its channel wider rather than deeper. The gradient of a mature river is less steep than young rivers, and the water flows more smoothly. Examples of mature rivers are the Thames, Mississippi, and Ohio rivers.
A stream that is longer and wider is usually considered a BROOK or a RIVER.
Two two largest Tributaries of the Mississippi River are the Missouri River and the Ohio River. The Missouri River intersection is just below St. Louis and essentially doubles the size of the River. The Ohio River (which is joined by both the Cumberland River at Smithland Ky. and the Tennessee River at Paducah Kentucky) joins the Mississippi River at Cairo, Illinois about 950 Miles above the Head of the Passes. The Ohio River combined with the Mississippi forms what is referred to as the lower Mississippi River and again it doubles in size. There are no locks and dams on the lower Mississippi River. The Ohio River is actually as wide if not wider than the Mississippi River at their junction. A large part of that is due to the Cumberland and Tennessee Rivers both very large Rivers in themselves joining the Ohio. The Cumberland joins about 62 miles above the mouth of the Ohio and the Tennessee joins the Ohio River only about 50 miles above the junction with the Mississippi River. Two more good size rivers the Illinois River joins the Upper Mississippi and the Arkansas River joins the lower. There are many more smaller rivers which join. I answered this in a question naming all the Tributaries of the Mississippi River. Captain Jim Turner
Mature river is a river with a gradient that is less steep than those of youthful rivers and flows more slowly than youthful rivers. A mature river is fed by many tributaries and has more discharge than a youthful river. Its channels erode wider rather than deeper. An example being the Mississippi River. Youthful river is a river with a steep gradient that has very few tributaries and flows quickly. Its channels erode deeper rather than wider. An example being the Ebro River.
Yes
a stream gets wider when it gets older and the water erodes the bed of the river to make it wider
It is called a river
yes
Because most of the water falls from rain and gets wider and longer every time it rains and flows,
