Types Of Oceans

An ocean is a major body of Seawater (salt water)The Earth's oceans cover approximately 71% of the Earth's surface, 361,000,000 square kilometers (139,000,000 sq mi), and can be as deep as of 10,923 meters (6.787 mi)

Earth's Oceans (World Ocean):

  • Pacific Ocean
  • Pacific Ocean which separate Asia from the Americas. The Pacific Ocean is the biggest of the Earth's oceanic divisions. It extends from Arctic in the north to Antarctica in the south, bounded by Americas in the east and Asia and Australia in the west.

  • Atlantic Ocean
  • Atlantic Ocean which separate the Americas from Europe and AfricaThe Atlantic Ocean is the second largest ocean in the worldThe Kiel Canal (Germany), Oresund (Denmark-Sweden), Bosporus (Turkey), Strait of Gibraltar (Morocco-Spain), and the Saint Lawrence Seaway (Canada-US) are main strategic access waterways

  • Indian Ocean
  • Indian Ocean which separate India from Africa. The Indian Ocean is the third largest ocean in the world. Four critically important access waterways are the Suez Canal (Egypt), Bab el Mandeb (Djibouti-Yemen), Strait of Hormuz (Iran-Oman), and Strait of Malacca (Indonesia-Malaysia).

  • Arctic Ocean
  • Arctic Ocean which border the northern continents and encompasses the far North including the North pole. The Arctic Ocean is the smallest ocean in the world. The Northwest Passage (US and Canada) and the Northern Sea Route (Norway and Russia) are two important seasonal waterways.

  • Southern Ocean
  • A verdict by the International Hydrographic Organization in the spring of 2000 delimited a fifth world ocean - the Southern Ocean - from the southern portions of the Atlantic Ocean, Indian Ocean, and Pacific Ocean. The Southern Ocean extends from the coast of Antarctica north to 60 degrees south latitude, which concur with the Antarctic Treaty Limit.
