ECONOM 1051 Lecture Notes - Axial Tilt
Document Summary
1. till unsorted sediment deposited directly by ice (material dumped by melting glaciers directly; poor sorting by size of sediments: stratified drift relatively well sorted sediment laid down by glacial meltwater; relatively good sorting, landforms made of till, moraines layers or ridges of till, moraines produced by alpine glaciers i. ii. lateral moraine formed along side of valley medial moraine formed between two valley glaciers that have joined; pile of sediment in the middle, other types of moraines i. end moraines terminal or recessional; mark former position of front of a glacier ground moraines undulating layers of till deposited as the ice front retreats. Common to both valley glaciers and ice sheets: drumlins smooth, elongated, parallel hills, steep side faces the direction ii. from which the ice advanced, occur in clusters called drumlin fields, formation not fully understood, landforms made of stratified drift, outwash plains with ice sheets and valley trains when in valley.
