Question

Which planet in our solar system is known as the "Red Planet"?

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

Hint:

{Mars = Red Planet} because its surface contains iron oxide (rust).

Answer 1

The Correct Option is B

Concept: Mars is commonly known as the "Red Planet" because of its reddish appearance when observed from Earth. The red color is caused by the presence of iron oxide (rust) on the planet’s surface. Iron minerals in Martian soil react with oxygen and form iron oxide, giving the planet its distinctive red color.
Step 1: Identify the planet with reddish appearance.
Mars appears red due to iron oxide dust covering much of its surface.
Step 2: Eliminate other options.

• Venus is known for its thick atmosphere and extreme temperature.
• Jupiter is the largest planet with prominent gas bands.
• Saturn is known for its extensive ring system.

Thus, the planet known as the Red Planet is Mars.
