Summary

Story summary

Scientists from Utrecht University propose that blocks of dry ice create gullies on Mars.
Mars has a thin atmosphere dominated by carbon dioxide, which allows ice to form in winter.
As temperatures rise in spring, the ice sublimates and moves downhill, carving channels in the sand.
The findings were published in Geophysical Research Letters, detailing how these processes shape the Martian landscape.
