Answer 2

Answer:

Ocean movement is created by the governing principles of physics and chemistry. Friction, drag, and density all come into play when describing the nature of a wave, the movement of a current, or the ebb of a tide. Ocean motion is influenced by occurrences here on Earth that are familiar, like heat changes and wind. It also requires a shift in perspective to encompass the movement of planets, the Moon, and the Sun. Though it appears we live on a stable and stationary planet, we are, in fact, whipping through space around the Sun in an orbit and spinning on an axis. This planetary movement has a strong effect on how oceans move.

While the ocean as we know it has been in existence since the beginning of humanity, the familiar currents that help stabilize our climate may now be threatened. Climate change is altering the processes that propel water across the globe, and should this alter ocean currents, it would likely lead to a cascade of even more change.
