  1. Oceans Water, Waves & Underwater Ocean features

  2. What does the bottom of the ocean look like? Covered in sand?

  3. Covered in Plants?

  4. Covered with Mountains?

  5. Lets Take A Look Video of Ocean Floor

  6. Features of The Ocean Floor • The landscapes found deep beneath the ocean are as dramatic as any found onshore! JaggedPeaks muddy plains Trenches Mountains

  7. Basin • Low • Flat • Abyssal Plain • are made of fine sediments that have been washed off the surface of the continents for thousands of years. Continental rise • Moving upwards towards shore • Made of a mixture of sediments • Turbidity!!! --- Small underwater avalanches of sand and sediment • Less habitats

  8. Continental Slope • Steepest!!!! • Minimal Habitats Continental Shelf • Shallowest • What we see/walk on when we go to the beach • Lots of Habitats and Creatures • Warmer water ( sunlight) • Like a shelf !!........ before it drops off into deep ocean

  9. Trench • Underwater canyon • Deepest places on Earth • Coldest Seamounts • Underwater Mountains and Volcanoes • Those that surface above water are known as volcanic islands • Hawaii

  10. What about Landforms above water created by the ocean?

  11. Barrier Islands • Barrier islands are constantly on the move. • Migrating under the influence of changing • sea levels • storms • waves • tides • longshore currents. **They form when sediments piles up on itself and eventually reaches the surface.

  12. Barrier Islands • They move in a rolling fashion along the coastline. Sediment deposits on the back side Barrier island grows & elongates

  13. Now that we know what is under the water, lets look at the water characteristics & see how that water moves…..

  14. Ocean Water Characteristics

  15. Waves • A Wave is a rhythmic movement that carries energy through matter or space. • In oceans, waves move through seawater

  16. Crest – highest point of a wave Trough – lowest point of a wave Wave Height – vertical distance between the crest and the trough Wavelength – horizontal distance between two crests or two troughs

  17. Wave Motion • When a wave passes through the ocean, individual water molecules move up and down but they do not move forward or backward. Hey Guys, watch these videos! http://www.youtube.com/watch?v=bQrj0DNXjMY http://www.youtube.com/watch?v=7yPTa8qi5X8&feature=related

  18. So if a WAVE is the movement of energy…..Where does the energy come from?

  19. Wind • Wind blows across the water’s surface creating shear force Fetch- the distance the wind can blow over the water * The longer the fetch length and the faster the wind speed, the larger and stronger the wave will be.
