Martian Rainfall Changes Has Role In Shaping Planet: Study Reveals By Piyali Roy firstname.lastname@example.org | May 25, 2017 01:11 AM EDT A new research study reveals that heavy rain occurring on Mars is a reason for the shaping of the planet. Martian rainfall had a role in shaping Mars' impact craters and river-like channels in its surface, billions of years ago. The researchers involved in this study are from Smithsonian Institution and Johns Hopkins University Applied Physics Laboratory. As Phys.org cited, the study shows that any change in the atmosphere of Mars, resulting in Martian rainfall had an effect on the surface of the planet. It is very similar to the effect of heavy rain on the surface of the earth as seen. Mars has very similar geological features to the Earth and the moon, i.e. craters and valleys and all these were formed due to heavy Martian rainfall. In spite of the fact that there is a developing assemblage of proof that there was once water on Mars, it doesn't rain there today, means no Martian rainfall occurs today. The study reveals that it does not rain today but in the past, it used to rain in Mars, which was the main reason for changing the planet's surface. According to Elsevier, the study report on previous Martian rainfall has been published in the journal Icarus. Geologists Dr. Robert Craddock and Dr. Ralph Lorenz, who participated in the study, used methods to determine the effect of rain in the early Martian atmosphere. These scientists also analyzed the nature of heavy rainfalls in Martian atmosphere. To see how Martian rainfall on Mars has changed with respect to time, the scientists needed to consider how the Martian climate has changed. At the point when Mars initially shaped 4.5 billion years prior, it had a considerably more significant air with a higher weight than it does now. This weight impacts the measure of the raindrops and how hard they fall.
