Mars surface geology

Mars’ surface geology features a variety of landscapes shaped by volcanic activity, wind erosion, and ancient water. It has massive volcanoes like Olympus Mons, the tallest in the solar system, and deep canyon systems such as Valles Marineris. The planet's surface is covered with iron-rich dust that gives it a reddish appearance. Evidence of past water includes dried riverbeds and minerals formed in water. Impact craters from space collisions are common, and certain areas show layered sediments indicating environmental changes over time. Overall, Mars’ surface tells a complex story of geological activity and a wetter past.
