  • Water boils and freezes at 0°C under 610 pascals (triple point of water)
  • Polar ice caps, inlandsis, ice cliffs
  • Dry river beds; alluvial fans, rounded pebbles
  • Layers of river and lake sediments
  • Hydrated rocks including phyllosilicates (clays)
  • Shorelines surrounding the Northern Plains
