Here is how Mars’ Valles Marineris look in comparison to the United States
Although Mars is our closest planetary neighbor, it still holds many secrets and mysteries. One of the most amazing natural geological features of this planet is Valles Marineris.
Scientists believe that the Valles Marineris was not created in the same way as the Grand Canyon. The Valles Marineris is likely a crack in the planet’s crust instead of being formed by river currents.
