Martian glaciers were slowed by fast drainage and weak gravity, scientists suggest
"On Earth, this glacial motion has produced scoured landscapes in northern Europe and North America," Grau Galofre wrote."Mars lacks such large-scale glacial erosion even in areas with other signs of widespread glaciation."Instead, Martian landforms created by glacial melt and movement are mostly ridges and valleys with shallow, undulating channels.
Some glaciers on Mars might have had an assist from below. The research team hypothesized that to push the glaciers any faster, there would have had to be enough stress to make up for weaker gravity.is a phenomenon that happens when both temperature and pressure from the weight of the heavy ice above, known as, put enough stress on ice for it to start deforming.
