4. Circle Map (output) What do you know about the ocean?? 4

5. Oceans http://www.neok12.com/video/Oceans/zX0 17f6474005b547b02070a.htm 5

6. 6 The World’s Oceans 71% of the Earth’s surface is covered by ocean water.

7. 7 Oceans  The oceans are the Atlantic, Pacific, Indian and Arctic.  All the oceans and seas are actually one continuous body of water.

8. 8 Oceans  Scientists believe that the ocean was formed when volcanoes erupted giving off water vapor.  Over millions of years the vapor cooled and rained into low areas called basins. 8

9. 9 Properties of Ocean Water  Ocean water is a mixture of gases –oxygen, carbon dioxide and nitrogen ....and solids (dissolved salt!)  The salts come from rocks and erupting volcanoes

10. 10 Salinity  Salinity describes the amount of dissolved salt in the ocean.  The average salinity of ocean is 33-35 parts per thousand.

11. 11 Salinity Levels  The salinity is lower in areas where freshwater rivers run into the ocean.

12. 12 Quick Quiz (Output) 1. Identify the origin of the water in the Earth’s oceans. 2. Explain how salt gets into seawater.

13. 13 Tides  Tides are caused by the gravitational pull of the moon and the sun.  Although the sun is bigger in mass, the moon is closer, so the moon has a greater effect than the sun.

14. 14 High and Low Tides  The earth rotates it passes under the moon.  The part of the earth that is passing under the moon will have a high tide and so will the area directly on the other side of the globe.  The areas in between will have low tide.

15. 15 Tidal Range The tidal range is the difference between the level of the ocean at high and low tide.

16. Groups of Marine Life 16

17. Three Groups 1. Plankton- organisms that drift freely near the ocean’s surface. 17

18. Three Groups 2. Nekton- organisms that swim actively in open water. 18

19. Three Groups 3. Benthos- organisms that live at the bottom of the ocean. 19

20. Bell Work 1/27/15  1. What is salinity?  Salinity describes the amount of dissolved salt in the ocean.  2. What is the average salinity of the ocean?  33-35 parts per thousand 20 On your desk: 1. I.N. 2.Pencil/Pen 3.PRIDE Cards

21. Ocean Environments  The Pelagic Environment- the region near the surface of the ocean and at the middle depths. –Neritic Zone –Oceanic Zone  The Benthic Environment- the region near the bottom of the ocean –Intertidal Zone –Sublittoral Zone –Bathyal Zone –Abyssal Zone –Hadal Zone 21

22. Ocean Environments It is time to…… Do some research….. AND…… Make a FOLDABLE!!!!! 22

23. 23 Ocean Zones

24. 24 Ocean Zones Color BLUE Color DARK BROWN Color LIGHT BROWN CUT! Around the outside ONLY!

25. 25 Ocean Zones Pelagic Environment Benthic Environment Intertidal Zone Sublittoral Zone Bathyal Zone Neritic Zone Oceanic Zone CUT! Follow instructions!! Abyssal Zone Hadal Zone

26. Each Zone Page 52-57! 26 1. Description 2. Depth 3. What organisms live here? 4. Draw a picture of an organism found in that zone

27. Let’s do 1 together…  Intertidal Zone:  Step 1: Read about zone (as a class)  Step 2: Write Questions and Answers!  1. Description  2. Depth  3. What organisms live here?  4. Draw a picture of an organism found in that zone 27

28. Bell Work 1/28/15 28 2. Does the sun or the moon have a greater effect on tides? Why? –The moon! The sun is bigger in mass, but the moon is closer, so it has a greater effect than the sun. On your desk: 1. I.N. 2.Pencil/Pen 3.PRIDE Cards 1. What causes tides? –The gravitational pull of the moon and the sun.
