Answer:
So reservoir will take 455000 sec to raise 35 cm
Explanation:
We have given surface area of the reservoir = 650000 
Rate of flow = 0.5 m/sec
Height through which reservoir is raise = 35 cm = 0.35 m
So volume 
We have to calculate the time
Time is given by 
Eastern boundary currents are associated with the cooling off of the ocean waters. These currents originate from both of the poles, they bring cold, shallow, slow water towards the lower latitudes and cools of the water near the Equator. Once there they are warming up and move in the opposite direction as westward warm currents.
