Some curiosities: . The origin of the ocean´s names: . Atlantic Ocean: his name has mythological origin, derived from Atlas, son of the name of the God of the Seas - Neptune. .

It is located at the North Pole, in the constellation Ursa Minor. The name also it is derived from the Greek word arctos, which means "bear". . Southern Ocean: is another ocean whose origin of the name is geographical. This, in turn, receives this name because it is located in the opposite geographical position to the Arctic Ocean (Arctic - Antarctic)
We begin by observing water in liquid and solid state
The water in the solid state takes place when subjected to very low temperatures.
To observe the water at another stage , we put a container and heated it. The boiling water quickly began to evaporate. We have found that the water was disappearing from the container and vapor rising like a cloud.
To arrive at another stage , we put a cold vessel above steam and quickly began to turn the vapor back into a liquid (condensation) and we observed the droplets fall. It was raining
