The colour of the surface of Mars is red because of the presence of large amounts of chemical compounds in it. What is the name of that compound?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Iron oxide.
The red color of the surface of Mars is primarily due to the presence of iron oxide, commonly known as rust. This compound forms as iron in the Martian soil reacts with oxygen over time, creating a reddish hue that gives the planet its distinctive appearance. The abundance of iron oxide is a key factor in the planet's landscape, influencing both its color and its geological features. This characteristic red coloration has fascinated scientists and astronomers for centuries, contributing to Mars's nickname as the "Red Planet" and driving ongoing exploration efforts to study its composition and history.
