Scientists are studying the traces on the surface of Mars, which left the boiling water.
Unusual black marks on the surface of the hills on Mars were left not just salty water flows, as recently announced by NASA, and boiling water evaporating at very low temperatures, according to a paper published in the journal Nature Geophysics.
Such flows occur in spring during the melting of water ice. The researchers assumed that liquid water is responsible for the strange appearance of bands arising through Martian hills during the summer. It only remained unknown how temporal streams of salt water were able to modify the Geology of the landscapes of the planet.
The researchers decided to conduct a series of laboratory experiments in a chamber that could reproduce the physical conditions on the Martian surface. The researchers observed that as melt water interacts with the underlying deposits of sand.
They put the ice block on the top of the slope and studied what happens when it melts in terrestrial and Martian conditions.
It turned out that water, which arose after the melting of ice, will not simply flow down the slope, moving across the Sands of Mars, and even to the same boiling, steaming active in “space” at that moment, when it rises to the surface of the soil.
This evaporation process was so active that he strewed the grains of sand around, causing landslides and other processes, which made traces of water in the laboratory is almost indistinguishable from how they look dark stripes on the real Mars.
Scientists believe that some of the other landforms on Mars that indicate the presence of water on its surface today, could occur in much the same way.
