As a stream's carrying capacity decreases, which of the following sizes of sediments will be deposited last?

width, depth, and velocity all increase

As the discharge of a stream increases, which of the following also happens?

increases

Consider the equation Q = wdv. According to the equation, if Q (discharge) remains constant, but w and d decrease (as when a channel becomes more narrow and shallow), the velocity will

True

Stream width, depth, and velocity are all responsive to discharge rates.

fluvial

Stream-related processes are termed

deranged

The glaciated shield regions of Canada and northern Europe have disrupted surface drainage patterns that are called ________ patterns.

at the center and near the surface, corresponding with the deepest parts of the stream channel.

Which of the following rock types is most affected by fluvial solution?

braided channels

Which of the following stream channel forms is likely to develop when aggradation greatly exceeds erosion?

dendritic

Which of the following stream channel types is likely to develop on gently sloping surfaces composed of rocks or sediments with approximately the same resistance to erosion? (Also assume that there are no structural controls on the pattern's development.)

radial

A central peak, or a dome of a volcanic mountain, generally produces ________ drainage patterns.

false

A flood recurrence interval of 100 years means that floods of that size will occur only once every 100 years.

true

False

Nickpoints migrate downstream.

Amazon river

Of the world's largest rivers, which has the greatest discharge?

False

Rivers make excellent political boundaries since they are clearly defined landform features.
