Question

The green planet in the solar system is:

• A. Mars
• B. Uranus
• C. Venus
• D. Earth

Hint:

Uranus is called the "green planet" because its atmosphere contains methane, which gives it a bluish-green appearance.

Answer 1

The Correct Option is B

The planet Uranus is often referred to as the "green planet" due to its distinctive bluish-green color, which is visible when observed through telescopes. This color is primarily caused by the presence of methane in its atmosphere, which absorbs red light and reflects blue and green wavelengths.
Here's why the other options are incorrect:
- Option (1): Mars: Mars is known as the "Red Planet" because of its reddish appearance, caused by iron oxide (rust) on its surface.
- Option (2): Uranus: This is the correct answer, as Uranus has a bluish-green hue due to the methane in its atmosphere, giving it the nickname "green planet."
- Option (3): Venus: Venus is often called the "Evening Star" or "Morning Star" due to its bright appearance in the sky. Its surface is covered in thick clouds of sulfuric acid, giving it a yellowish-white appearance. - Option (4): Earth: While Earth is sometimes referred to as the "Blue Planet" due to its abundant water, it is not typically described as a "green planet." The green color associated with Earth comes from its vegetation, but this is not how it appears from space.
