Oceans currents are significant in thermal regulation. The ocean waters at the equator are warmer than those at the poles. This is due to the fact that the tropics receive direct sunlight throughout the year than the poles. The less dense warm currents move towards the poles on the surface waters while the cold denser waters from the poles move towards the equator on the ocean floor. This is expedited by the Coriolis effect of the earth’s rotation. These ocean currents transfer heat and distribute it hence regulating the globe’s climate.
The government maintains its efforts to clean up the river are on course. Water Resources Minister Nitin Gadkari said in December that the Ganges will be 70-80 percent clean within three months and 100 percent clean by March 2020.
