What evidence from “NASA’s Curiosity Rover Finds Clues to How Water Helped Shape Martian Landscape” is the most relevant support for the assertion that lakes may have once existed on Mars? (Select all that apply.)

A)“The great thing about a lake that occurs repeatedly, over and over, is that each time it comes back it is another experiment to tell you how the environment works,” Grotzinger said.
B)The rock layers—alternating between lake, river and wind deposits—bear witness to the repeated filling and evaporation of a Martian lake much larger and longer-lasting than any previously examined close-up.
C)This interpretation of Curiosity’s finds in Gale Crater suggests ancient Mars maintained a climate that could have produced long-lasting lakes at many locations on the Red Planet.
D)“We may see how the chemistry changed in the lakes over time. This is a hypothesis supported by what we have observed so far, providing a framework for testing in the coming year.”

Answer:

  • B)The rock layers—alternating between lake, river and wind deposits—bear witness to the repeated filling and evaporation of a Martian lake much larger and longer-lasting than any previously examined close-up.
  • C)This interpretation of Curiosity’s finds in Gale Crater suggests ancient Mars maintained a climate that could have produced long-lasting lakes at many locations on the Red Planet.

Option B supports the idea of a lake existing in Mars by explaining how the rock layers of the planet show evidence of a repeated filling and evaporation of a Martian lake. Option C, on the other hand, provides evidence of a climate that could have sustained lakes on Mars.

However, option A and D do not directly reference the existence of lakes on Mars and do not even discuss the planet  itself.
