hey,
Would you pls answer these questions?
Thanks
QUESTION 1
What does concave upward mean, in the context of a stream channel?
Concave upward describes the longitudinal profile of a stream — where the sections closest to the ocean have a low slope. Then, as the stream profile gets closer and closer to the headwaters, the stream channel gets progressively steeper.Concave upward describes the longitudinal profile of a stream — where the sections closest to the ocean have the steepest slope. Then, as the stream profile gets closer and closer to the headwaters, the stream channel gets progressively less steep.All of the other answers are correct, and thus this is the best answer.Concave upward describes the cross-sectional profile a meandering stream, where there are ridges called natural levees immediately adjacent to the stream. Then, there is a flat surface created by flood deposits called a floodplain. Lastly, the slope gets steeper and steeper as the profile reaches the hillslopes that surround a stream valley.

What is the discharge (Q) of a stream?
The amount of water that sinks into the ground underneath a streamThe volume water water, measured by multiplying stream area times stream velocity.The velocity of a stream.The volume of water the is supplied to a perennial stream by baseflow, measured over a period of time.

QUESTION 3
What part of a stream system typically supplies the load that a stream carries?
the lowest portions of a stream system where the stream enters a lake or oceanthe middle of a stream systemAll of the other answers are correct, and thus this is the best answer.in the headwaters (mountains) of a stream system

QUESTION 4
What does it mean when a stream has a graded profile?
Graded stream profiles are not flat. They have undulations of high points and low points. The graded profile is a line that connects all of the high points in a stream channel.A graded stream stream has a smooth concave-upward longitudinal profile from the base level to the headwaters without any breaks (e.g. waterfalls, rapids) in the profile.A graded stream profile is one where a dam has created a change in the longitudinal profile of a stream.Graded stream profiles are not flat. They have undulations of high points and low points. The graded profile is a line that connects all of the low points in a stream channel.

What is an avulsion?
a slow change in the location of a meandering stream that takes place as the point bar pushes the stream, bit-by-bit, further and further towards the cut banka sudden switch in the location of a meandering stream that takes place during a big enough flood to overtop a stream banka sudden break in the longitudinal profile of a stream, typically created by waterfalls or stream rapidsa slow change in the location of a meandering stream that takes place as the cutbank erodes back bit-by-bit
