The acids and the moving water erode the banks and the bottom of the river.
No some rivers can become wider, smaller, deeper and narrower. not all of them follow the same pattern.
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.
mature rivers are wider insted of deeper. the gradient isn't that steep. mature rivers have few water falls and have many tributaries . they have more load then younger rivers.
They get wider by wheatering out the surronding rocks , erosion.
A river that erodes its channel deeper rather than wider is typically classified as a narrow, steep-gradient river, often found in mountainous or hilly regions. These rivers possess a high flow velocity, which increases the force of water against the riverbed, leading to vertical erosion. This process deepens the channel as sediment is carried away from the bottom rather than from the sides. Consequently, such rivers create V-shaped valleys, contrasting with wider, meandering rivers that erode laterally.
Usually yes, because it has more water to store, therefore more erosion, which makes it deeper and wider.
Is a river with a gradient that is less steep than those of youthful rivers and flows more slowly. It is fed by many tributaries and has more discharge than a youthful river and its channels erode wider rather than deeper.
a river gets wider from source to mouth a river gets deeper from source to mouth a rivers load gets smoother from source to mouth a rivers load gets smaller from source to mouth the velocity of a river stays the same from source to mouth
