How Carbon dioxide Helped Water Flow On Mars? Unlocked Now!

In many aspects, Mars is eerily similar to Earth, but particularly in the way its surface features resemble Earth's deserts. Features like valleys, canyons, fan-like sand and rock washes, and long, twisting gravel ridges known as eskers are common to both Earth and Mars. Water flows through them all, leaving their marks on the surface for millennia and continuing to do so long after the water has subsided. Geologic Seasons Trapped On Mars ~Life on Mars~ Still Very Debatable ! (Source: Google Images) Scientists know that these features were created by moving water, thus that is not the mystery of Mars. The question that has baffled them for decades, however, is how and when Mars could store such vast volumes of liquid water.Research scientist Peter Buhler of the Planetary Science Institute has modeled a novel hypothesis: that carbon dioxide smothered the even larger water ice glaciers on Mars' surface and caused them to melt out in rivers thousands of miles long after condensing out of the planet's atmosphere in a glacier that was almost 0.4 miles (0.6 kilometers) high. His findings were published in the Journal of Geophysical Research: Planets on November 1. Recent Still Capturing some exciting citing on Mars (Source: Google Images) Buhler's model aims to fill in a gap in Martian history ~  What led to the planet warming up enough to melt enough water to create the numerous, diverse river systems that still traverse its surface today?  Buhler stated in a press statement that “the best hypothesis at this time is that there was some unspecified global warming event, but that was an unsatisfactory answer to me, because we don't know what would have caused that warming.”Buhler's concept is based on a cycle that scientists think is still occurring on Mars now, which is brought on by the gradual shift of the planet's rotational tilt, rather than climate warming. Mars is inclined on its axis, just like Earth. At the moment, Mars' tilt is 25°, which is comparable to Earth's 23°. However, Mars wobbles much more than Earth does over hundreds of thousands or millions of years. According to some research, it can swing from upright (0°) to 80°, with its poles almost pointing toward the Sun. Closer Microscopic Stills Showing Some Vital Insights (Source: Google Images) Similar to seasonal variations but over a geologically long time span, this wobble propels a carbon dioxide cycle. As the Sun bakes the equatorial regolith, carbon dioxide escapes into the atmosphere, cools, and eventually condenses as ice on top of the water-ice caps close to the poles. The ice that contains carbon dioxide sublimates back into the atmosphere in the poles as the Sun warms them more directly. Until the following cycle, the carbon dioxide is subsequently absorbed by the regolith close to the equator. A large portion of Mars' carbon dioxide is currently trapped in the regolith, which covers each rock grain with a coating that is only one molecule thick.  Understanding The Science Behind ~ A Diagrammatic Illustration ( Source: Google Images)   Buhler examined how this cycle would have functioned some 3.6 billion years ago, earlier in Mars' history. Scientists believe that many of Mars' river characteristics first developed during this period, when the planet's atmosphere was thicker and contained considerably more carbon dioxide. According to the model, in this prehistoric environment, warming of the equatorial regions leads to the condensing of carbon dioxide into a layer that is 0.4 miles (0.6 km) thick at the poles. This sheet is situated above a water-ice cap that is 2.5 miles (4 km) thick, which is roughly equivalent to the present-day Martian south pole ice cap. The water ice top is insulated and under pressure from the thick carbon dioxide, which traps heat from underneath and melts the water ice beneath. According to Buhler, this process occurred multiple times over a period of around 100 million years, resulting in the diverse river landscape that is currently visible on the surface of Mars.Buhler's concept offers a novel explanation using cycles that are still present on Mars now, giving us a new perspective on the history of our nearest neighbor, which is both similar and distinct from our own. However, only a time machine could definitively tell us what created Mars' ancient rivers.
