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 causes downcutting of a stream?

Downcutting, also called erosional downcutting, downward erosion or vertical erosion is a geological process by hydraulic action that deepens the channel of a stream or valley by removing material from the stream’s bed or the valley’s floor. The steeper the gradient, the faster the stream flows.

What is 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. Examples are the Brazos, Trinity and Ebro rivers.

Which factors increase the amount of downcutting?

Whether a river erodes its channel or deposits sediment depends primarily on three factors: base level, the amount of water passing a certain point in the river (its discharge), and the amount of sediment supplied to the river.

Which is stream channel cutting process most likely to create features called potholes?

The straight channel has a higher gradient and more friction than the natural channel. The natural channel had a lower gradient and higher friction than the straight channel. The natural channel had a lower gradient and higher friction than the straight channel. Which stream-channel-cutting process is most likely to create features called potholes?

Which is feature characterize wide streams and valleys?

A ________ drainage pattern is common in areas where the bedrock is criss-crossed by a series of joints and/or faults. Which of the following features characterize wide streams and valleys?

Which is the lowest base level for most streams?

T/F: The lowest base level for most streams is sea level. T/F: A V-shaped valley and no floodplain indicate a youthful, downcutting stream.

Where are stream patterns developed only on growing mountains?

A ________ stream pattern is developed only on growing mountains like volcanoes or where the land surface is tectonically doming upward. What is the drop in water surface elevation divided by the distance the water flows?
