Glacial striations on bedrock. Rocks embedded in the bottom of a massive glacier scratched the rock underneath as the glacier moved along. Even though there is no ice present today, these scratched lines are evidence that glaciers were here in the geologic past.lacial striations are parallel to the handle of the hammer. Look at how the lines all go the same direction. Click to Enlarge. About : The scratch marks on the schoolyard are formed by the process shown on top -- a broom dragged along over wet tar.
1 End Moraines and Terminal Moraines are deposited at the low elevation end of a glacier as the ice retreats due to ablation (melting). 2  Lateral Moraines are deposits of till that were deposited along the sides of mountain glaciers. during glacial periods much sea water was tied up in glaciers so sea level was lower. 2  during interglacial periods sea level was higher due to melting of the ice. 3  during interglacial periods land that were covered with ice during a glaciation are uplifted due to removal of the weight of the ice.
