Why is MARS red?


The rocks on the surface of Mars contain iron, which has turned to a kind of rust.This red, dusty material covers the planet’s surface and is sometimes blown into huge dust storms.

On Mars, the ‘red Planet’, dust is so fine that it hangs in the thin air as a permanent haze, causing the sky to be pink rather than dark blue. Sometimes the surface of Mars disappears from sight beneath clouds of dust raised by Martian winds.
