Valles Marineris on Mars is the most striking valley in the solar system. It is the largest canyon in the solar system, spanning over 4,000 km in length, 200 km in width, and 7 km in depth. It is so vast that it could easily span across the entire United States if it were on Earth. It is believed to have been created by both tectonic and volcanic activity on Mars. Valles Marineris on Mars is the most striking valley in the solar system, stretching over 4,000 km long, up to 7 km deep, and up to 200 km wide. It is more than ten times longer and five times deeper than the Grand Canyon on Earth. The valley was likely formed by tectonic activity and may have also been influenced by volcanic activity and erosion.
