Because fresh water is constantly be evaporated from the ocean and then replaced by rivers, the salinity of the oceans . A. increases

B. doubles

C. remains balanced

D. decreases

Because fresh water is constantly be evaporated from the ocean and then replaced by rivers, the salinity of the oceans remains balanced.

Explanation:

When evaporation takes place in sea water then of course there will occur an increase in salinity.

But as this evaporated water is replaced by water coming from rivers. As a result, the raising salinity is counter balanced by the water coming from rivers.

Hence, salinity remains balanced in sea water.

Thus, we can conclude that because fresh water is constantly be evaporated from the ocean and then replaced by rivers, the salinity of the oceans remains balanced.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
