Why can permanent liquid water not exist on Mars today?
A) Both atmospheric pressure and surface temperature are too low, and any water would be in the form of ice or vapor.
B) The surface of Mars is too porous to allow water to remain on the surface.
C) Water would react with the CO2 in the atmosphere to form carbonic acid, which would react quickly with the rocks on Mars to destroy the water.
