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 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 calander. So, to keep an accurate count, an extra day is added at the end of february every four years.

What are the most precious stones?

When the magma cools, the material which it contains solidifies in the form of crystals. Precious stones are crystals with particular characteristics of colour, hardness and the way they can reflect the light. They are used in making jewellery.

What How Why

How is the height of a mountain measured?

To measure the height of mountain, the surface of the sea is taken as the point of reference. The height of the mountain is the distance between the top of the mountain and the surface of the sea.

What is an electric current?

An electric current is a passage of electrons from one electrified body to another which is less charged. When too many electrons are generated, they can move.

What How Why

Why does iron go rusty?

Rust forms on the surface of iron objects when they are exposed to the air. It is the product of a chemical reaction called oxidization. The more the object is exposed to the air, the more rapidly rust spreads.

How fast can a dog run?

A Greyhound can run at a speed of 64km per hour, a Weimaraner , once used for hunting wolves and wild boar, can reach speed of up to 56 km per hour in a chase. Many breeds of dog which were once bred for hunting are now more common as pets than hunting Dogs.
