What are three features of the youthful stage of the river?
Youthful or Upper stage Steep slope, moving very fast, lots of erosion and the valley has steep sides. 2. Mature or Middle stage Gentle slope, river beginning to slow down, some erosion, deposition begins and the valley begins to widen. 3.
What is the youthful stage of a river?
The youthful stage of the river is when water flow is the quickest. Waterfalls, potholes, V-shaped valleys and interlocking spurs are features of the youthful stage, and these features are due to erosion. The flow becomes gentler during the mature stage, and the river widens.
What are the characteristics of a youthful river?
Youthful river – a river with a steep gradient that has very few tributaries and flows quickly. Its channels erode deeper rather than wider. Mature river – a river with a gradient that is less steep than those of youthful rivers and flows more slowly than youthful rivers.
What is the characteristic feature found in mature stage of river?
In the mature stage of a river the slope becomes gentler and the river becomes much wider as it is joined by many tributaries. The river is also carrying a load now that has been eroded from further upstream. Meanders are bends or curves which are found in the mature stage (middle course) of a river.
In which stage many tributaries meet the river?
The larger, or parent, river is called the mainstem. The point where a tributary meets the mainstem is called the confluence.
Which of the following is commonly associated with tributaries?
Which of the following is commonly associated with tributaries? the velocity and turbulence of the current.
What are the 3 stages of a river called?
These categories are: Youthful, Mature and Old Age. A Rejuvenated River, one with a gradient that is raised by the earth’s movement, can be an old age river that returns to a Youthful State, and which repeats the cycle of stages once again. A brief overview of each stage of river development begins after the images.
How do youthful mature and old age rivers differ?
“Mature” rivers flow more slowly than young rivers because they are less steep, have more creeks that flow into them and are wider than they are deep. “Old” rivers are very wide, with a gentle slope and have water that flows much more slowly than younger rivers.
What is tributary of a river?
A tributary is a freshwater stream that feeds into a larger stream or river. The larger, or parent, river is called the mainstem. The point where a tributary meets the mainstem is called the confluence. Tributaries, also called affluents, do not flow directly into the ocean.
What do you mean by tributary?
Definition of tributary (Entry 1 of 2) 1 : a stream feeding a larger stream or a lake. 2 : a ruler or state that pays tribute to a conqueror.
What is river tributary?
What is a river and its tributaries called?
A watershed is an entire river system—an area drained by a river and its tributaries. It is sometimes called a drainage basin.
What are the characteristics of the youthful stage of the river?
At the youthful stage the river is flowing fast down steep gradient, therefore there is much more evidence of erosion at this stage. A very common feature of erosion is interlocking spurs (picture) which are formed when the river meets a block of hard rock it cannot flow through or erode down.
What is the upper stage of a river called?
The upper stage of a river is also called the youthful stage or mountain stage. The velocity and speed of the stream are very high because the slope here is steep. The vertical erosion is the most dominant work here. The valley is formed here. The place where a river starts is called a source.
What are the different stages of river development?
These categories are: Youthful, Mature and Old Age. A Rejuvenated River, one with a gradient that is raised by the earth’s movement, can be an old age river that returns to a Youthful State, and which repeats the cycle of stages once again. A brief overview of each stage of river development begins after the images.
Which of the following is a common characteristic of Old Rivers?
Their course is no longer straight and widened floodplains are a common characteristic. An old river rests in an almost flat valley as a result of the many years of erosion that have taken place. The Nile and the Ganges are examples of old rivers.
