Document Summary

Pleistocene comes before the holocene glacial and interglacial periods. Traces ( moraines eg ( glacial features ) are gone and replaced by other glacial features glacial maximum - when the sheets were at their maximum extent. *know the names of the di erent ice sheets of canada the ice ow goes all around based on how thick they are , and where they are located. End moraine - found at terminus of glaciers. Proglacial lake - (in front o ) the adding of ice causing the lithosphere to sink is called subsidence the retreat of the glacier happens faster than isostatic rebound. Champlain sea - saline water coming from the atlantic ocean than glaciers went south and east it was then depressed (being pushed down) due to subsidence (weight of glaciers) than the champlain has retreated due to isostatic rebound. Post glacial isostatic adjustment - ottawa 2 mm.
