If the ice caps at the north and south pole of the the earth melted how would you expect the salinity of the ocean to change?

PLATO answer - become less salty because a greater amount of water would hold the same amount of salt

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
