Which of the following planet appears blue from the outer space because of its two-thirds surface is covered by water?
Show answer & explanation
Correct answer: A
Explanation
When viewed from space, Earth appears as a beautiful blue sphere; for this reason, it is known as the 'Blue Planet.' The reason for this is that approximately two-thirds of Earth's surface (about 71%) is covered by water.
When sunlight passes through the atmosphere and strikes the oceans, the water absorbs the red light and reflects the blue light, causing the planet to appear blue.
Other planets, such as Mars (red) or Venus (bright yellow/white), appear in different colors due to the composition of their surfaces and atmospheres.
