Unknown Facts about Seas and Oceans | Unknown Facts

We know that 1/3 of the earth is surrounded by water. Mainly these are oceans and seas but, 3% it contains water for drinking from the source of the river. All thing we know about oceans and seas up to this only. I know you are bad to hear this but this is the truth. If we compare our knowledge with the Galaxy or else to oceans and seas then you will find that we know less about Oceans and Seas compare to Galaxy or something else.

Maybe you know that there is a difference is seas and oceans but if you don’t know then I will tell you this in brief. But before this, I want to discuss with you some more stuff about oceans and seas. So let me start, Earth is the only known planet or moon to have large bodies of liquid water on its surface. Well, you glad to know that our planet is the only planet that has enough atmospheric pressure to prevent liquid surface water from evaporating into space not too hot or not too cold.

Although we don’t yet know of any other planets with liquid water oceans, it’s likely that they do exist and we just haven’t found them. In our own solar system, there is growing evidence that the planet Mars may have liquid water not on the surface but underground. There is also strong evidence that liquid oceans may be hidden beneath the thick icy surfaces of three of Jupiter’s moons (Europa, Callisto, and Ganymede) and two of Saturn’s moons (Titan and Enceladus).

 

What are Seas and Oceans?

An ocean (from Ancient Greek Ὠκεανός, Okeanós) the sea of classical antiquity) is a body of saline water that composes much of a planet’s hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean.

A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, “the sea” is the interconnected system of Earth’s salty, oceanic waters—considered as one global ocean or as several principal oceanic divisions.
