Title: What is the gradient of a stream?
Post by: lyss96 on Feb 24, 2018
What is the gradient of a stream? What will be an ideal response?



Q. 2 - Distinguish sheet flow from channel flow. What will be an ideal response?



Q. 3 -

In what ways can water be temporarily stored, from a few years to a few thousand years, on the land
  areas before returning to the oceans? What will be an ideal response?





Q. 4 - Briefly explain what property of water makes hydrologic cycling possible. What will be an ideal response?



Q. 5 - What powers the hydrologic cycle? What will be an ideal response?



Q. 6 - In the hydrologic cycle, what happens to the precipitation that falls on the land? What will be an ideal response?

(Answer to question 1 )  

Stream gradient is the slope over which the stream flows, the vertical drop through which the stream
moves divided by the horizontal distance the water moves.



(Answer to question 2 )  

With sheet flow, water moves in a more-or-less continuous film over the surface. With channel flow,
the runoff is confined to long, troughlike depressions.



(Answer to question 3 )  Water can be stored in lakes, snowfields, glaciers, or as groundwater.

(Answer to question 4 )  

Water changes phase from liquid to solid to vapor all within the normal range of Earth surface
temperatures.



(Answer to question 5 )  The hydrologic cycle is powered by the sun.

(Answer to question 6 )  It becomes runoff, it evaporates or is transpired, or it is absorbed (becomes groundwater).
