What is the water component of the earth?
One of the main components of Earth’s interdependent physical systems is the hydrosphere. The hydrosphere is the sum of Earth’s water, in the ocean, the ground, on the surface, and in the air. Approximately 71 percent of Earth’s surface is covered in water.
Where is the water on Earth?
Earth’s water is (almost) everywhere: above the Earth in the air and clouds, on the surface of the Earth in rivers, oceans, ice, plants, in living organisms, and inside the Earth in the top few miles of the ground.
Is Venus Earth’s sister?
Venus is very similar to Earth in size and mass – and so is sometimes referred to as Earth’s sister planet – but Venus has a quite different climate. Venus’ thick clouds and closeness to the Sun (only Mercury is closer) make it the hottest planet – much hotter than the Earth.
Who is the brother of the earth?

Was the Earth ever completely water?
The ancient Earth may once have been completely covered in water, new research suggests. In a study published in Natural Geoscience, researchers examined a chunk of ocean crust located in northwestern Australia ‘s outback that is approximately 3.2 billion years old.
