Answer 1

A smooth, egg-shaped hill left behind by a glacier is called a drumlin.
Drumlins are approximately 250 to 2000 meters long and 300 to 600 meters wide. Drumlin is glacial landform composed primarily of glacial till (unsorted glacial sediment), so internal composition of a drumlin is stratified sand, unstratified till or bedrock.
