The region around latitude 60 south is the only part of the Earth where the ocean can flow all the way around the world with no land in the way. The rule is simple - salt makes water heavier, so it sinks. b. mountain ranges Some span hundreds to thousands of miles across vast ocean basins in well-defined flows. Two years ago, oceanographers made a surprising discovery: Not only have oceans been warming because of human-driven climate change, but the currents that flow through them have acceleratedby some 15% per decade from 1990 to 2013. e. Soil B, The sinking of land due to the overpumping of ground water supplies Being both cold AND salty makes it really dense, so it can sink very far. Differences in salinity also affect sea life.
