Question

A.The Mars is red in colour. Why?
​

Answer 1

Hey!

Mars is red-coloured because of the Iron Oxide (rust) compounds the rocks and soils contain!

Step-by-step explanation:

They turn red after the reaction with the little oxygen in the atmosphere as it was exposed...making the Oxide of Iron. This reflects the light from the sun, making it appear like a red star in the sky.

HOPE THIS HELPS!

Answer 2

Several rocks on Mars are made of iron in which when they're exposed to the great outdoors, the rocks oxidize turning the color to red.

Step-by-step explanation:

The planet's color contain a lot of iron oxide which is the same compound giving the color of blood and rusting its hues.
