22. Why is the earth called the "water planet"? |
|
Answer» Explanation: But among the planets ORBITING the Sun, Earth is clearly the "WATER planet." Water occurs on its surface as liquid, ice, and gas. This fact is APPARENT when Earth is viewed from space—so-called "blue marble" pictures. Earth is RIGHTFULLY called a water-world: far more than half of our planet is covered in water. There's also water underground, in rivers, and in the ATMOSPHERE. ... That's because the ocean covers 71 percent of Earth's surface. |
