Glacial landscapes in the UK
Amount of the World's land surface cold environments cover
UK current cold environments
are limited to parts of Northern and upland Scotland and there is regular snow cover in winter in Aviemore today
20,000 years ago
much of the UK will have been covered in ice as part of a much larger Arctic ice sheet.
Times when the temperature has dropped significantly and ice advances
During glacial periods
global temperatures drop to an average 11°C from the current 15°C.
22,000 years ago
Peak of last glacial period peaked and since 12,000 years ago we have seen warming.
Times when temperatures are warmer for extended periods of time and are marked by the retreat of ice to higher altitudes or Latitudes.
South of Thames
In the UK in last ice age there would have been areas of permanently frozen ground (permafrost) and tundra vegetation which we find much further north in Europe today.
Huge meltwater rivers
would also have taken sediment far away from this ice environment.
North of the Thames In the UK in the last ice age would have been covered in Ice
Would have transformed the river valleys and rounded hills underneath through various erosion, transport and deposition processes.
