PLEASE HELP! I NEED THIS SOON What is the reason the higher average surface densities are found in the southern hemisphere?

In fact, the salinity decreases as we move closer to the equator due to the rains the region consistently receives. The land mass is more in the northern hemisphere. This is could be one reason for increased salinity in the northern hemisphere. Land heats up and cools down faster than water (oceans).
