rain takes away the dirt on the side of the river along with the current of water
A stream that is longer and wider is usually considered a BROOK or a 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
When a river flows, particles within the water wear away the sides of the river bank. This happens as they meander (when a river curves around corners) this causes water to push on the outer sides and push even more, wearing away in great curves. They can, however, get wider by weakening the banks. This however, depends on the circumstances, amount of rainfall, soil pH and other factors.
A river curves back and forth because it becomes wider then the river erodes land on one side and deposits sediments along the other side this causes the river to develop curves P.S. i'm 9!
yes
The river delta.
no.
It is about 300 meters on average
A mature river
Yes it does, one of the reasons is erosion. Hydraulic action and corrosion erode the bends of the river making the outside bend wider. :P
