GLOBAL Ocean

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

72% of Earth’s surface

97% of Earth’s water is saltwater

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

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

97% of all the water on Earth

Distribution of Earth’s Water Percentage Type of Water Amount 100% (2- 2 liter bottles) All the water on Earth 4000 mL 97% ( of the 2-2 liter bottles) Saltwater 3% ( of the 2-2 liter bottles) All the freshwater on Earth 68.7% of the freshwater Frozen water in Ice Caps and Glaciers 30 % of the freshwater Groundwater 1.3% of the freshwater Surface Water ( rivers, lakes & swamps)

Pacific Ocean Largest, deepest oldest ocean Covers almost 1/3rd of Earth’s surface Average depth- 4.3 km Natural resources: oil, gas, metal nodules, sand, gravel , fish Over 25 000 islands Marianas Trench 11 022 m

Pacific Ocean

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

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

Atlantic Ocean Puerto Rico trench is the deepest part, 8 650 meters deep Many rivers flow into the A.O. Few islands

Atlantic Ocean Also known for: Broadest continental shelf summer and fall hurricanes The Bermuda Triangle The Mid- Atlantic Ridge The shipwreck of the Titanic

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

Indian Ocean Deepest part is the JAVA Trench, 7 258 m deep

Southern Ocean Runs from the coast of Antarctica to 60⁰S Very deep, between 4000 – 5000 m Large and possible giant oil and gas fields, Mn nodules, sand, gravel, squid, whales, seals, krill

Southern Ocean South Sandwich Trench is the deepest part, 7235 meters Huge icebergs

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

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

SEAS A large body of salt water, smaller than an ocean that may be partly or nearly surrounded by land Examples: Sargasso Sea Caribbean Sea Mediterranean Sea Pencil in # in green

GULFS An area of saltwater bordering on and lying within a curved coastline, usually smaller than a SEA but larger than a BAY Examples : Gulf of Mexico Gulf of Alaska Persian Gulf Pencil in letter in orange

BAYS An INLET of the OCEAN or part of the OCEAN bordering on land and partly surrounded by land Examples : Chesapeake Bay Bay of Bengal Hudson Bay Pencil in letter in red/pink

STRAITS A passageway of water connecting two large bodies of water Examples: English Channel Davis Strait Korea Strait Pencil in letter in purple
