This is the world's third largest ocean and is border by Africa and the Atlantic Ocean in the West, and the Pacific ocean in the east.The Arabian Sea is also a part of this ocean.The shores of Indian ocean are not well cut and hence it is not easy to make a harbour on it.
The Arctic ocean is also known as the Arctic Sea.It is a great mass of water around the North Pole and ships cannot navigate through it because it remains frozen for most of the year.The most interesting thing about the Arctic ocean is that the North pole is located there.Robert Edwin Peary is believed to have been the first explorer to reach the North Pole.
The Atlantic,Pacific and Indian Oceans meet in the Antarctic region near the South Pole.This ocean is formed by the junction of these three oceans.It forms a kind of circle that surrounds the Antarctica ocean.
