Oceans (Thermohaline Circulation Model/Oceanic Conveyor Belts (Functions,…

- - - - Sunlight, life (fish and coral)
      - Oil + gas
      - Biotic + abiotic resources
    - - Mostly flat terrain
      - Guyots and seamounts
      - Gold/silver - precious metals
    - - Formed in subduction zone
      - Oceanic crust forced down by continental crust, but doesn't get filled by magma
    - - eg. Mid-Atlantic Ridge
      - Formed when two plates move away from one another (constructive margin)
      - Magma wells up from the 'gap'
    - - Older undersea volcano
      - Eroded when it was above sea level
      - Rounded peak
    - - Younger undersea volcano
      - More active/sharp and pointy peak
    - - Formed when two plates move away from one another (constructive plate margin)
      - Slower than ridge formation > Magma wells up at the sides, creating a valley
