Clues

  • ________ Earth - when large areas of the Earth are permanently covered in ice (8)
  • __________ Earth - no continental glaciation due to warming caused by high levels of greenhouse gases (10)
  • A period of geological time which started approx. 2.6 mil yrs ago (10, 6)
  • Periods of warming when glaciers retreat causing depositional features to form (13)
  • Portions of the Earth's surface where water is in solid form, usually as snow or ice (10)
  • Regions or areas of the Earth that are currently, or show evidence of having been, glaciated (7, 10)
  • Short-term retreats of ice during glacials when it is temporarily warmer (13)
  • The changes in the Earth's climate over long periods of time (7, 6)
  • The era of ice 2 mil - 12000 yrs ago (11, 5)
