Scientists Use the Most Graphic Way to Show How Much Water There is on Earth

How much water is there on earth? Scientists present it in the most graphic way. Our description of the earth has always been a beautiful blue planet. From space, we can see almost all the ocean on the earth. So how much water is there in the ocean that covers most of the Earth's surface? According to the scientists, the most vivid way to show it!

How much earth is made of water? The fact is very little. Although the ocean covers 70% of the earth's surface, the ocean is very shallow relative to the radius of the earth. Well, how big is the water on earth? Let's take a look at this picture below.

This theme shows that if the earth's surface and all the water around it are integrated into spheres, the radius of the sphere is only about 700 kilometers, smaller than half of the radius of the moon, but a little larger than that of Titan five;

Much of the moon, similar to the outer solar system, is a major component of Titan's five. However, why such a large amount of water appears on the earth, whether or not there is a great deal of water under the surface of the earth is still the subject of scientific research.
