We know that our ‘Olympus Mon’ Sun is the largest mountain in the Solar System.
What about the biggest valley? That too on Mars .. !! Let’s introduce it to those who do not know.
At 7 miles deep, 2,500 miles long, and 120 miles wide, the Valles Marineris is the largest canyon in our solar system.
Let’s start with the history of the name. The name is derived from the Latin word meaning Mariner Valley. (Launched May 30, 1971 and reached Mariner 9 on November 14, 1971.)
There is no clear answer as to how this happened. However, the current conclusion is that it was formed by the erosion caused by water flowing through a crack caused by the movement of the plate, like a massive displacement on Earth.
