For the first time, researchers explored how much changes in Mars' geologic were different from the same processes on Earth, using data from NASA's Muriosity Mars and astronaut observations during its stay at the International Space Station.
The key conclusion of this particular article is that the seemingly weak power of wind erosion controls the process that exposes stratificational layers of mountain rock on Mars, which is very different from geological processes on our planet, where layers of rock are exposed through a dynamic combination of tectonic activity that lifts up pieces of land and water erosion of rivers that hit rocks from the top down.
"The wind is mainly responsible for the erosion of Mars, and it acts as a feathered broom that has been operating for hundreds of millions and even billions of years. This is very different from the Earth, for example, where the extremely severe mountains of San Gabriel are created by rainwater streams that scatter the landscape over relatively short periods of geological time," explains John P. Grotzinger, Professor of Geology.
Despite the fact that the Mars InSight landing module has observed small marshes, there are no tectonic plates on the Red Planet that cause most earthquakes, but the surface of Mars is almost entirely eulogic or wind erosion.
Wind erosion plays a key role in the mountain cycle on Mars, especially in earlier periods, until 3 billion years ago, when rocks in the Gale crater were only formed.
