The document discusses the five major oceans: 1. The Pacific Ocean is the largest ocean and contains the deepest point on Earth. It has many volcanoes and islands of volcanic origin. 2. The Atlantic Ocean is S-shaped and lies between four continents, making it important for travel and trade. It was formed when the continents broke apart at the Mid-Atlantic Ridge. 3. The Indian Ocean is the world's third largest and warmest ocean, located between Asia, Africa and Australia. It became important for travel between Europe and Asia after the Suez Canal opened.

12. Write a short note on THE ARCTIC OCEAN
 It is the Smallest ocean in the world.
 It Spreads around North Pole.
 During winter it is completely frozen.
 During Summer, the ice melts and forms large flat
floating islands and ice bergs.
 The Arctic ocean is connected to both the Pacific Ocean
and the Atlantic ocean.

13. THE ANTARCTICOCEAN

Antarctica and is formed by the
