WebSurface currents; are wind-driven movements of water at or near the ocean's surface, and thermohaline currents; are the slow deep density-driven currents that affect the vast bulk of seawater beneath the pycnocline. Ocean water represents the largest body of water within the global water cycle (oceans contain 97% of Earth's water). Evaporation from the ocean moves water into the atmosphere to later rain back down onto land and the ocean. Oceans have a significant effect on the biosphere. The ocean as a whole is thought to cover approximately 90% of the Earth's biosphere. Oceanic evaporation, as a …
