The video explains how Mars' red soil was formed. Millions of years ago, iron-rich rocks on Mars were eroded by flowing water. The oxygen in the water reacted with the iron to create iron oxide, a process known as oxidation or rusting. Over time, this iron oxide spread across the planet, giving Mars its distinctive red color.

How did the iron oxide-rich soil affect the appearance of Mars?

• It caused Mars to look yellow.

• It turned Mars into the Red Planet.
