Question

Which planet is known as the Blue Planet?

• A. Venus
• B. Earth
• C. Jupiter
• D. Saturn

Hint:

Earth is called the "Blue Planet" because of its abundant water bodies, which give it a blue appearance when viewed from space.

Answer 1

The Correct Option is B

The planet Earth is known as the "Blue Planet" due to its abundant water bodies, which cover approximately 71% of its surface. When viewed from space, Earth appears predominantly blue because of the reflection of sunlight off the vast oceans and water bodies. This distinctive blue color makes Earth unique among the planets in our solar system.
Here's why the other options are incorrect:
- Option (1): Venus: Venus is often referred to as the "Evening Star" or "Morning Star" due to its brightness in the night sky. Its surface is covered in thick clouds of sulfuric acid, giving it a yellowish-white appearance, not blue.
- Option (2): Earth: This is the correct answer, as Earth is known as the "Blue Planet" because of its extensive water coverage and the way it reflects light from the Sun.
- Option (3): Jupiter: Jupiter is the largest planet in our solar system and is primarily known for its massive size and the Great Red Spot, a persistent storm on its surface. It does not have a blue appearance.
- Option (4): Saturn: Saturn is famous for its prominent ring system and is often described as having a pale yellow hue due to its composition of hydrogen and helium. It is not known as the "Blue Planet."
