1. GLOBAL Ocean

2. What are 3 ways you can express numerically that Earth is a WATER PLANET ?

3. 72% of Earth’s surface

4. 97% of Earth’s water is saltwater

5. 1/4000th of Earth’s Mass 1/800 of Earth’s volume

6. Arthur C. Clarke
“How inappropriate to call this planet Earth, when clearly it is Ocean.”

7. 97% of all the water on Earth

8. Create a ‘VINE’ video Calculate # of mL for each category
Fill container
Label with post it note or white board
Film with VINE app ( be careful of background items and noise)
Post on #scitwi
View others VINES at end of period

12. Pacific Ocean

13. Pacific Ocean Deepest sea floor in the world 10 911 meters
Deep sea trench formed by the plate tectonic movement called SUBDUCTION

14. Atlantic Ocean 2nd largest, youngest ocean
Contains oil, gas, placer deposits, sand , gravel, precious stones, metal nodules, placer deposits, fish marine mammals
Icebergs a natural hazard
Piracy occurs

The shipwreck of the Titanic

17. Indian Ocean 3rd largest , warmest, saltiest ocean
Natural resources include oil, gas, fish ,shrimp, sand, gravel, placer deposits, metal nodules
High risk of piracy
Known for strong, shifting monsoonal flow of wind and water

18. Indian Ocean
Deepest part is the JAVA Trench, m deep

19. Southern Ocean Runs from the coast of Antarctica to 60⁰S
Very deep, between 4000 – 5000 m

Huge icebergs

21. Arctic Ocean Smallest ocean
Natural resources include sand, gravel, placer deposits, oil , gas, placer deposits, metal nodules, fish, marine mammals
Fragile ecosystem
Thinning ice

22. Arctic Ocean mostly ice covered Mainly surrounded by land
Largest % of continental shelf
Shallowest ocean
Many icebergs

23. SEAS
