Worlds Oceans

VIEWS: 1 PAGES: 13

									OCEANS
• The oceans cover 70.8 percent of planet Earth.
• By far the largest of the four oceans, the Pacific Ocean covers
nearly one-third of the globe.
• All the continents could be placed into the Pacific Ocean, and there
would still be room left over.
• Average depth is 13,000 feet.
• The hourglass shaped Atlantic Ocean covers approximately 20
percent of the Earth's surface and is the second largest of the 4 oceans.
• It extends from the North Pole southward for 10,000 miles to the
Antarctic continent.
• Average depth of the Atlantic Ocean is 12,000 feet.
• The greatest depth is 28,374 feet (Puerto Rico Trench).
• The Mid-Atlantic Ridge divides the sea floor nearly through the
center and stretches from the polar regions of the North to Antarctica
in the South.
• The Mid Atlantic Ridge was created by the splitting apart of the
super continent of Pangaea 190 million years ago.
• The Indian Ocean stretches southward from India to Antarctica.
• It is triangular and bordered by Africa, Asia, Antarctica, and,
Australia.
• The average depth of the Indian Ocean is about 12,750 feet.
• The deepest part is 24,440 feet in the Java Trench.
• The Indian Ocean, like the Atlantic Ocean is divided by a mid-
ocean ridge that separates the basin into nearly equal portions.
 Centered approximately on the North Pole, the ARCTIC
  Ocean is the smallest of the world's oceans.
              ARCTIC OCEAN




 Maximum   depth is 18,050 feet.
 TheArctic Ocean is divided into two nearly equal
 basins: The Eurasia basin & the Amerasia basin.
              ARCTIC OCEAN




 TheArctic Ocean is surrounded by landmasses of
 Eurasia, North America, and Greenland, and is unlike the
 other three oceans because of the perennial ice cover.
