  1. Warm Up, October 28th, 2013 What are four unique properties of water? Explain why water sticks together. Why does water expand when it freezes? Organize the ocean into three zones and explain why you placed them where you did.

  2. “Latin and Greek” Derivatives (II)* DerivativeTranslation 1) inter- between, among 2) intra- within 3) tid- time, period 4) ichthy- fish 5) -berg mountain, hill

  3. The Ocean – Discovery Education What fraction of the planet is covered by oceans? How do scientists study the oceans? Why has so much of the ocean has gone unexplored? What role do the oceans play in weather and climate? How do we use the ocean as a resource?

  4. The Intertidal Zone* - The zone closest to the shore, sometimes referred to as the shoreline. The intertidal zone is usually above water at low tide and below water at high tide.

  5. The Intertidal Zone

  6. The Neritic Zone* - Above the continental shelf. The neritic zone is the area of the ocean extending from the low tide mark to the end of a continental shelf.

  7. The Neritic Zone

  8. The Deep Zone* - Sometimes referred to as the oceanic zone. The deep zone begins offshore, starting at the end of a continental shelf. The deep zone is 65% of all ocean water.

  9. The Deep Zone

  10. Continental Shelf* - The submerged border of a continent that slopes gradually down.

  11. Phytoplankton* - Microscopic organisms that inhabit the upper, sunny layers of oceans and most fresh water. Phytoplankton produce most of the world’s oxygen.

  12. Why are oceans SALTY? Eroding land - salt in rocks.

  13. Why are oceans SALTY? • Eroding land Volcanic emissions

  14. Why are oceans SALTY? • Eroding land • Volcanic emissions Atmospheric Deposition (All sorts of stuff gets up in our air and comes back down .)

  15. Why are oceans SALTY? Biological and chemical reactions on the sea floor • Eroding land • Volcanic emissions • Atmospheric deposition

  16. Our ocean has 3 ecosystems: • Intertidal Zone (aka…littoral zone aka…shoreline)

  17. Our ocean has 3 ecosystems: • Shoreline (aka…littoral zone…intertidal zone) • Neritic zone (aka…Nemo/Sponge Bob territory…)

  18. Our ocean has 3 ecosystems: • Shoreline (aka…littoral zone…intertidal zone) • Neritic zone (aka…continental shelf)

  19. Our ocean has 3 ecosystems: • Shoreline (aka…littoral zone…intertidal zone) • Neritic zone (aka…continental shelf) • Deep ocean (aka…benthic zone)

  20. Our ocean has 3 ecosystems: • Shoreline (aka…littoral zone…intertidal zone) • Neritic zone (aka…continental shelf) • Deep ocean (aka…benthic zone)

  21. Our ocean has 3 ecosystems: • Shoreline (aka…littoral zone…intertidal zone) • Neritic zone (aka…continental shelf) • Deep ocean

  22. Our ocean has 3 ecosystems: • Shoreline (aka…littoral zone…intertidal zone) • Neritic zone (aka…continental shelf)
