While this model does not depict the ocean circulation patterns that results from atmospheric wind and density differences in water masses, it summarizes the key concepts involved in explaining this process. 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. Ocean waters are constantly on the move; understanding how and why they move is not an easy task. b. subduction zone Being both cold AND salty makes it really dense, so it can sink very far.

Country E Coastal and sea floor features influence their location, direction, and speed. a. extinction of species is a natural process, and the process is always faster on islands More saline water masses are found in areas where there is a lot of evaporation because salt is left in the water, or in polar areas because as ice forms, salt is left in the water. For example, the shallow, speedy currents could ultimately limit how much heat the ocean can absorb, causing more of that excess heat to remain in the atmosphere. This heat is then transported by currents and re-radiated, influencing regional air temperatures and climates all over the globe. b. pesticides from agricultural fields d. a kingsnake has coloration similar to the dangerous coral snake e.

The adjective thermohaline derives from thermo-referring to temperature and -haline referring to salt content, factors which together determine the density of sea water. And given that the speedup is driven by the steady drumbeat of warming, it means these trends are likely to continue in the futureas long as human emissions of greenhouse gases continue. apes final Flashcards | Quizlet The study suggests climate change will continue to speed up across ocean currents, potentially limiting the heat the ocean can capture and complicating migrations for already stressed marine life.
