Presentation Transcript

  1. The 5 Oceans • Oceans cover about 70% of the Earth's surface. • The oceans contain roughly 97% of the Earth's water supply. • The oceans of Earth serve many functions, especially affecting the weather and temperature. • They moderate the Earth's temperature by absorbing incoming solar radiation (stored as heat energy).

  2. The 5 Oceans • The always-moving ocean currents distribute this heat energy around the globe. • This heats the land and air during winter and cools it during summer. • Until the year 2000, there were four recognized oceans: the Pacific, Atlantic, Indian, and Arctic. • In the Spring of 2000, the International Hydrographic Organization came up with a new ocean, the Southern Ocean.

  3. The 5 Oceans • There are also many seas (smaller branches of an ocean); seas are often partly enclosed by land. • The largest seas are the South China Sea, the Caribbean Sea, and the Mediterranean Sea.

  4. The Pacific Ocean • The Pacific Ocean is the largest of the five oceans on Earth. • The name “pacific” has been derived from the Latin name “Mare Pacificum”, which means “peaceful sea”. • Pacific Ocean was so named by Ferdinand Magellan, a Portuguese explorer.

  5. The Pacific Ocean • The Equator passes through the ocean, dividing it into 2 parts - North Pacific Ocean and South Pacific Ocean. • The Pacific Ocean is larger than all of the Earth's land area combined. • The Mariana Trench in the western North Pacific is the deepest point in the world. • You could fit Mt. Everest inside and the top would not stick out of the water.

  6. The Pacific Ocean • The average depth of Pacific Ocean is 14,000 ft. • There are more than 25,000 islands in the Pacific Ocean. • Almost the entire rim of the Pacific basin is ringed with volcanoes and earthquake areas. • The Great Barrier Reef in Pacific Ocean, off the coast of Australia, is the longest reef in the world.

  7. The Atlantic Ocean • The Atlantic Ocean is the second largest ocean in the world. • It is slightly less than 6.5 times the size of the US. • The name 'Atlantic' is derived from the legendary island of “Atlantis”. • Atlantic Ocean was the first ocean to be crossed by ship and airplane.

  8. The Atlantic Ocean • In South Atlantic, there is a wide stretch of ocean between the tips of South Africa and South America, which causes huge waves & continuous strong winds, known as the "Roaring Forties". • The largest island in Atlantic Ocean is Greenland. • A triangular area in Atlantic Ocean, called The Bermuda Triangle, is held responsible for mysterious shipwrecks, disappearances and air crashes.

  9. The Indian Ocean • The Indian Ocean is the 3rd largest ocean. • It’s name is derived from the country India. • The Indian Ocean is the warmest ocean in the world. • But, the warm water resists the growth of phytoplankton except for a few spots. • Therefore, life thriving in the ocean is limited.

  10. The Indian Ocean • Indian Ocean transports a heavy traffic of petroleum and petroleum products, from the oilfields of the Persian Gulf and Indonesia. • The ocean provides major sea routes connecting the Middle East, Africa, and East Asia with Europe and the Americas. • Approximately 40% of the world's offshore oil production comes from the Indian Ocean. • Fishing in Indian Ocean has been restricted to subsistence level.

  11. The Arctic Ocean • The Arctic Ocean is the smallest ocean. • It is also the shallowest. • Throughout the year, the ocean is largely covered with a sheet of sea ice due to very low temperatures. • The Arctic Ocean is nearly completely surrounded by Eurasia and North America.

  12. Arctic Ocean • The Arctic Ocean's cold sheet of floating ice is quarters to seals, polar bears and arctic fox. • The Arctic Ocean's ice sheet is four times as large as the state of Texas. • More fish live along the edges of the Arctic Ocean than anywhere else on the Earth. • The Arctic is the only place on the Earth where polar bears live.

  13. The Southern Ocean • The Southern Ocean is also named Antarctic Ocean, South Polar Ocean or Great Southern Ocean. • Icebergs are a further serious problem for navigation in this ocean, especially, during the Antarctic winter (May-October). • The Southern Ocean surrounds the entire continent of Antarctica. • It includes the southern portions of the Pacific, Atlantic, and Indian Oceans. • The Southern Ocean was created in the year 2000.
