Water Bodies

How the Oceans Form?

The Earth began as a cloud of dust and hot, shinning gas. When our planet began to cool, its surface solidified, surrounded by clouds of water vapours. When these vapours condensed and began to fall like rain, oceans formed in the hollows of the Earth’s surface.
Oceans are huge expanse of water which separates the Earth’s continents. The largest Ocean is the Pacific Ocean, second largest is the Atlantic Ocean and third largest is the Indian Ocean.

Number of Oceans!

While there is only one global ocean, the vast body of water that covers 71 percent of the Earth is geographically divided into distinct named regions. The boundaries between these regions have evolved over time for a variety of historical, cultural, geographical, and scientific reasons.

There are four main oceans on Earth: the Pacific, the Atlantic, the Indian, and the Arctic. These oceans have no real borders, and water flows freely between them. Smaller parts of these oceans are called seas, gulfs, and bays.

Oceans Division

Pacific Ocean: Separates Asia and Oceania from the Americas
Atlantic Ocean:Separates the Americas from Eurasia and Africa.
Indian Ocean:Washes upon southern Asia and separates Africa and Australia.
Southern Ocean: encircles Antarctica.
Arctic Ocean: covers much of the Arctic and washes upon northern North America and Eurasia

Interesting things about Oceans

  • As well as being the largest ocean, the Pacific Ocean is also the deepest.
  • Eighty per cent of all pollution in seas and oceans comes from land-based activities.
  • In Pacific Ocean is the point furthest from any land, a distance of 2575Km.
  • About 70 percent of the planet is ocean, with an average depth of more than 12,400 feet
  • The longest mountain range in the world is under water. Called the Mid-Oceanic Ridge, this chain of mountains runs through the middle of the Atlantic Ocean and into the Indian and Pacific oceans.
  • Much of the life in the oceans, as on land, is invisible to the naked eye.
  • More than 97% of all our planet's water is contained in the ocean
  • The worlds oceans contain nearly 20 million tons of gold.

What How Why

What is a leap Year?

It takes the Earth 365 days and six hours to orbit around the Sun. The Six extra hours cannot be counted on the calendar. So, to keep an accurate count, an extra day is added at the end of February every four years.
