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.
