Q: Why Earth is called the blue planet?
  • A. Because of two-thirds surface covered by water
  • B. Because of water laden clouds in the atmosphere
  • C. Because of pollution in the atmosphere
  • D. None of these
Correct Answer: Option A - The earth is the third nearest planet to the sun. In size, it is the fifth largest planet. It is slightly flattened at the poles. Its shape is described as a Geoid. Geoid means an earth-like shape. Conditions favourable to support life are probably found only on the earth. From the outer space, the earth appears blue because its two-thirds surface is covered by water. It is, therefore, called a blue planet.
