Precipitation and snow was common in Mars

Scientists have uncovered evidences that suggest that snow and precipitation may have been a common occurrence in Mars at some point in the past, says Nature World News.

Runoff from orographic precipitation - moisture carried part of the way up a mountain by prevailing winds and deposited as snow on the slopes - appears to have shaped valley networks branching across the martian surface, researchers at Brown University reported Tuesday, according to UPI.com.

With the knowledge from this study that precipitation was important in carving the valleys, the answers to those additional questions could provide important insight into the climate on Mars billions of years ago, informs Daily News&Analysis.
