flow-like features on mars.

flow-like features on mars.  while some scientists say they are probably produced by liquid water or brine on the red planet’s surface, other investigators interpret these features as dry mass movements, stirred up by alternative geological processes.

whatever the cause, these slope streaks are among the few known examples of current geologic activity on mars. many scientists agree that water is likely to have flowed across ancient mars. however, whether it exists as a liquid on the planet’s surface today is still a subject for further investigation.
