This topic is an essential part of Physical Geography and Geomorphology, particularly important for UPSC, State PSC, and other competitive examinations. Glaciers are moving masses of ice and snow that flow down mountain slopes due to gravity and melting processes. As glaciers move, they act as powerful agents of erosion, transportation, and deposition, significantly modifying the landscape. The lecture explains the two major processes of glacial erosion: • Plucking – when moving glacier ice pulls rock fragments from the bedrock. • Abrasion – when rock debris carried by glaciers scrapes and polishes the surface beneath. These processes lead to the formation of several distinctive glacial erosional landforms, which are commonly asked in UPSC Geography and Physical Geography exams. 📚 Key Landforms Covered in This Lecture • Cirque (Corrie) – Bowl-shaped depression formed due to glacial erosion on mountain slopes. • Tarn Lake – A lake formed when a cirque fills with water. • Arête – A sharp knife-edge ridge formed between two cirques. • Col – The lowest point or saddle between two cirques or peaks. • Horn – A pyramidal peak formed when multiple glaciers erode a mountain from different sides. Understanding these glacial geomorphological features helps explain how glaciers reshape mountains and influence the topography of Earth’s surface.
