Document Summary

These processes tend to act together in particular environments. Mass movement occurs in all conceivable environments, regardless of whatever else is going on. Pleistocene rock: bare rock polish that has been grooved, etched in by pebbles that are in the ice sheet, grooves are referred to as striations. Nowadays, here ice occurs in major amounts, that is generally where people don"t live. If they are there, it is because they of their heritage or of research. Ice sheets and glaciers tend to have an indirect present-day impact on people. A lot of landforms of countryside we occupy are of glacial origins. People worldwide are going to be affected by ice indirectly as the ice sheets melt (present retreat) As they melt, sea levels go up, erosion at higher levels. There was at one time, much more ice around, at even our latitudes, as a consequence of the ice-age (pleistoceine epoch)
