What is an ocean?


An ocean is a very large area of salt water. Most of the Earth is covered
in ocean.


There are five oceans in the world:


  • Pacific Ocean
  • Atlantic Ocean
  • Indian Ocean
  • Southern Ocean
  • Arctic Ocean


Do you know where each ocean is in the world? Answers further down the page.


The Pacific Ocean


The Pacific Ocean is the biggest ocean in the world. It reaches from North and South  America to Asia and Australia.

The Pacific Ocean is surrounded by a line of volcanoes known as the Ring of Fire.

It is also home to the Great Barrier Reef, which is the largest coral reef in the world. Challenger Deep, the deepest point on Earth, is in the Pacific Ocean.


The Atlantic Ocean


The Atlantic Ocean is the second biggest ocean in the world. It reaches from North and South America to Europe and Africa.

The Atlantic Ocean is huge, but only half the size of the Pacific Ocean. The Mid-Atlantic Ridge, the longest mountain range in the world, is underwater in the Atlantic Ocean.



The Indian Ocean


The Indian Ocean is the third biggest ocean in the world. It is named after the country of India.


The Indian Ocean is home to many endangered sea creatures, including turtles, seals and dugongs (also known as sea cows).


The Southern Ocean


The Southern Ocean is the second smallest ocean in the world. It is also known as the Antarctic Ocean as it surrounds Antarctica.

It is the coldest and wildest ocean in the world.

The Southern Ocean is home to emperor penguins, blue whales, elephant seals, giant squid and the wandering albatross.



The Arctic Ocean


The Arctic Ocean is the smallest ocean in the world. It surrounds the Arctic.


Often, the Arctic Ocean is completely covered in ice. Polar bears live on the ice that covers the ocean and can swim in the water.
