The direction of these gyres would be the same as today, since the prevailing winds would probably be similar, and perhaps even more uniform since the ocean wouldn't be as broken up with continents. So it is likely that these gyres would be stronger than they are today. Within a glacier, the ice at the center and top moves fastest. In the ocean, deep water forms where surface water has the highest salinity. In the ocean, deep water forms where surace water is most dense.
Sea ice is less salty than sea water.
Due to friction, water always travels in the same direction as surface winds. A climate proxy refers to a process that changes the climate. Rivers are widest at their sources where water flows fastest. The term divide refers to a place where a river splits into two. Pick the best answer for each of the questions.
