Detailed explanation-1: -Mars, known as the Red Planet, is a mostly dry and dusty place. A variety of colors can be seen on the surface, including the predominant rusty red the planet is known for. This rusty red color is iron oxide, just like the rust that forms here on Earth when iron oxidizes – often in the presence of water.
Detailed explanation-2: -Well, a lot of rocks on Mars are full of iron, and when they’re exposed to the great outdoors, they ‘oxidize’ and turn reddish-the same way an old bike left out in the yard gets all rusty. When rusty dust from those rocks gets kicked up in the atmosphere, it makes the martian sky look pink.
Detailed explanation-3: -Like Earth, Mars has ice caps at its poles. Water reaches the poles as vapor and is frozen into thin layers that build up thick deposits. Mixed with this water is dust picked up by the wind, so the caps have bright and dark layers of “clean” and “dirty” ice.
