Currently, the majority of water on Mars is tucked away in its ice caps, but once upon a time, it was abundant on this planet, and now research shows that unnecessary lakes may have cut the planet’s dramatic canyon.
Like Phys.org reported billions of years ago, the water once had gusted through huge rivers on Mars that emptied into craters that eventually became large seas and lakes.
New research carried out by the University of Texas in Austin has proved that sometimes these craters lakes themselves were so filled with water as the swollen lakes ended up overflowing from their pools, which would have caused floods that were large enough to end up on creating the canyons of the planet. In fact, it is believed that some of these floods on Mars would have been so high that canyons could have formed in as little as a few weeks.
The new study’s author, Tim Goudge, a postdoctoral research at the UT Jackson School of Geosciences, stated that his new research reveals geological activities that floods may have had a far greater impact than platonic tonics when it comes to forming the features we see today on mars.
Researchers already know that many of the craters on Mars were once filled with water and converted into paleolakes. Over 200 of these paleolakers have been discovered next to outlet channels, which sometimes range hundreds of miles in distance, but before these new researchers could not decide if these canyons were formed quickly or over long periods of time, which could have lasted millions of years.
By looking at photographs from NASA’s Mars Reconnaissance Orbiter satellite, researchers carefully analyzed topography of 24 paleolakes, crater rims and their sockets and found evidence of flood events here. In fact, one of the paleolakers studied was the Jezero Crater, which is currently considered a possible landing ground for the Mars 2020 landlord.
As Goudge noted: “This tells us that things that differ between planets are not as important as the basic physics of the overflow process and the size of the pool. You can learn more about this process by comparing different planets instead of just thinking about what’s happening on earth or what’s happening on Mars. “
The new study describing how the Marshanians were probably formed by abundant lakes has been published in Geology .
