Answer 2

The Earth is nicknamed as a 'Blue Planet' because nearly 71 percent of its surface is covered by oceans.

Step-by-step explanation:

• The Earth is covered by a unibody made up of oceans which span 71% of the Earth's total surface area.

• These oceans appear dark blue in color when viewed from the space.

• The depth of the oceans and the scattering of light are the factors responsible to make the oceans appear blue.

• Thus, it is because of the dominance of the blue colored oceans on the 'surface of the Earth', the Earth is nicknamed as a blue planet.
