Why is earth called a blue planet?

Why do we call the earth a Blue Planet?

Answer 1

Water is an essential component of all life forms that exist over the surface of the earth. The creatures on the earth are lucky that it is a water planet, otherwise, we all would have no existence. Water is a rare commodity in our solar system. There is no water in the sun or anywhere else in the solar system. The earth, fortunately, has an abundant supply of water on its surface. Hence, our planet is called the ‘Blue Planet’.
