Understanding Oceanography: The Major Oceans, Salinity, and Ocean Floor Features

This guide delves into the fascinating world of oceanography, highlighting the three major oceans: the Atlantic, Pacific, and Indian. It explores key concepts such as ocean salinity, which contains approximately 35 parts per thousand of dissolved salts, and the classification of oceanic zones, including the surface, thermocline, and deep zones. Additionally, it covers ocean floor topography, detailing features such as submarine canyons, continental shelves, slopes, abyssal plains, trenches, and coral reefs, illustrating the dynamic relationship between land and ocean.

Presentation Transcript

  1. OCEANOGRAPHY

  2. THEMAJOROCEANS ATLANTIC, PACIFIC, AND INDIAN

  3. SALINITY THE AMOUNT OF DISSOLVED SALTS IN THE OCEAN WATER (35 PARTS /1000)

  4. 96% THE % OF THE OCEAN THAT IS PURE WATER

  5. SURFACE ZONE WHERE THE WATER IS MIXED BY WAVES & CURRENTS ( AT LEAST 100 M DEEP)

  6. THERMOCLINE ZONE OF RAPID TEMPERATURE CHANGE (NO SPECIFIC DEPTH)

  7. DEEP ZONE ZONE FROM THE BOTTOM OF THE THERMOCLINE ON DOWN (NOT FOUND IN ARCTIC OR ANTARTIC OCEANS) WATER TEMPERATURE JUST ABOVE FREEZING

  8. TOPOGRAPHY DESCRIPTION AND SHAPE OF THE OCEAN FLOOR

  9. SUBMARINE CANYONS UNDERWATER CANYONS

  10. SHORELINE BOUNDARY WHERE LAND AND OCEAN MEET

  11. CONTINENTAL SHELF RELATIVELY FLAT PART OF THE CONTINENT MARGIN COVERED BY SHALLOW OCEAN WATER

  12. CONTINENTAL SLOPE THE EDGE OF THE CONTINENTAL SHELF THAT DROPS SHARPLY

  13. CONTINENTAL RISE SEPARATES THE CONTINENTAL SLOPE FROM THE OCEAN FLOOR

  14. CONTINENTAL MARGIN WHERE THE UNDERWATER EDGE OF THE CONTINENT MEETS THE OCEAN FLOOR

  15. ABYSSAL PLAINS LARGE, FLAT AREAS ON THE OCEAN FLOOR

  16. SEAMOUNTS UNDERWATER MOUNTAINS (IF ABOVE THE WATER THEY ARE CALLED ISLANDS)

  17. GUYOTS FLAT TOP SEAMOUNTS

  18. TRENCHES LONG, NARROW CRACKS IN THE OCEAN FLOOR

  19. MID-OCEAN RIDGES UNDERWATER MOUNTAIN RANGES FORMED BY VOLCANIC ACTION

  20. CORAL REEFS LIMESTONE STRUCTURES SURROUNDING VOLCANIC ISLANDS

  21. FRINGING REEF REEF TOUCHES SHORELINE OF THE VOLCANIC ISLANDS

  22. BARRIER REEF REEF SEPARATED FROM THE ISLAND BY A SHALLOW LAGOON
