Data returned by the Odyssey Mars Rover suggest that these slope streaks are generally found on the sides of hills and mountains in Martian craters, and that their formation may be caused by frost formed by carbon dioxide at low temperatures

Because Mercury does not have an atmosphere to play a role in insulation, so the temperature of the back side of Mercury can be as low as minus 172 degrees Celsius, and because of the proximity of the sun, the temperature of the sunny side of Mercury will soar to 432 degrees Celsius under the baking of the sun, so it can be seen that Mercury is simply a realistic version of the "world of ice and fire"
