Glaciation

Glaciaion  Glaciation is study of ice and its impact on the environment. The ice age in Britain lasted from about one million years ago to about 20000 years ago.



 A glacier is a natural accumulation of land ice showing movement at some time. Many times during Earth's history, great ice sheets waxed and waned over the surface. The onset of a period or stage of glaciation is due to a change in Earth temperature an circulation.

Glacial Erosion

This is a picture of Glacial Erosion.

A glacier is a moving body of ice. The glacier forms when more snow and ice falls than melts and evaporates from previous years. The pressure of the increasing burden upon the snow converts the snow into ice. The glacier carries with it the dirt, gravels, rocks and boulders that it finds in its path as well as that embedded in the ice.
