Q. Which planet is known as the ‘Watery Planet’?

Explanation by: Mr. Dubey

Earth is known as the "Watery Planet" because about 71% of its surface is covered with water in the form of oceans, rivers, and lakes.

It is the only known planet in the solar system that has liquid water in abundance, which is essential for life.


Other Options Explained:

(A) Mercury – Has no water due to its extreme heat and lack of atmosphere.

(B) Jupiter – A gas giant with no solid surface; it mainly consists of hydrogen and helium.

(C) Mars – Has evidence of frozen water and past liquid water, but not enough to be called a "watery planet."


Thus, the correct answer is (D) Earth.
