Question

Mars has been fascinating humans for many years, particularly after a mistranslation of the Italian word for “channels” into “canals”. Suddenly science fiction authors, scientists, and ordinary people began seeing Mars as an inhabited world, where the society was creating canals to deal with a drying climate.

While the ground truth of the surface is quite different, the planet still fascinates us. There are indications on it’s surface that it once had a warmer, wetter, climate. Which of the following surface features found on Mars that suggest the presence of running water on the surface of Mars in the past?
