Editing Ocean Circulation (section)

== <span style="color: #FFFFFF;">Understanding</span> ==
Ocean circulation is understood through '''Density''' and '''The Pump'''.

'''1. The Engine (Salt and Cold)''':
Why does the water "Move"?
* When water gets near the North Pole, it gets "Colder."
* When sea ice forms, it leaves the "Salt" behind in the water.
* This "Cold, Salty" water becomes "Very Heavy" and "Sinks" to the bottom of the ocean.
* This sinking acts like a "Pump" that pulls warm water from the Equator up to take its place.

'''2. The Heat Distributor''':
The ocean is the "Air Conditioner" of the world.
* It carries the sun's energy from the "Hot Middle" to the "Cold Ends."
* Because of the Gulf Stream, London is much warmer than Canada, even though they are at the same latitude.
* If the pump "Slows down," the heat "Stays in the Tropics" and the North "Freezes."

'''3. The Nutrient Cycle''':
Ocean circulation is how the ocean "Breathes" and "Eats."
* Upwelling brings "Fertilizer" (nutrients) from the deep to the surface, which is why the most famous "Fishing Grounds" are always near upwelling zones.
* Downwelling brings "Oxygen" to the deep, allowing weird "Deep-sea monsters" to survive 2 miles under the surface.

'''The 'Coriolis Effect'''': Because the Earth is "Spinning," the water doesn't move in a straight line. It "Curves" to the right in the North and to the left in the South. This is why ocean currents form giant "Circles" (Gyres) rather than just moving up and down.
