The extensive canyon system known as the Valles Marineris stretches along the Martian equator for over 2500 miles. It was formed by what kind of geological process?
Answer Tectonic plate action
While primitive, Mars has plate tectonics, just like Earth. The Valles Marineris was formed along the splitting of the surfaces near the equator, which opened it up to further erosion.
