Explanation / Answer

1. The answer is 97%, 97percent of water ion Earth is available in the oceans.

2.The water cycle is summary of ...........The processes include evoparation, Transpiration, precipitation,.....

3.The answer is b=1200 cubic feet/ second
Given width=w=30 feet, depth=d=10 ft, and velocity=v=4 ft/ s
Discharge=w*v*d
Discharge= 30*10*4
Discharge= 1200 cubic feet/ second

4.The answer is Hydrograph, and in general velocity and discharge increses downstream
