Final answer:
Evidence suggests the presence of flowing water on Mars' surface today, including seasonal changes in dark streaks, exploration of dried-out lake beds, and the presence of glaciers covered with dirt and dust
Step-by-step explanation:
There is evidence suggesting the presence of flowing water on Mars' surface today. One piece of evidence is the images from the HiRISE camera, which show seasonal changes in dark streaks called recurring slope lineae. These streaks are locations where salty liquid water flows on or just below the surface. Another piece of evidence comes from the Mars rovers, which have explored dried-out lake beds that contain sedimentary rocks with chemical evidence of evaporation and spheres rich in the mineral hematite. Additionally, high-resolution photos from orbit have revealed glaciers covered with dirt and dust in the mid-latitudes of Mars.
