What specific terminology is used in geomorphology to designate a narrow, steep-sided ridge formed between two adjacent glacial valleys that have been subjected to intense lateral and headward glacial erosion?

💡 Solution & Explanation

An arete is a sharp, knife-edge ridge of rock formed when two neighboring glaciers erode parallel U-shaped valleys toward one another. A cirque is an armchair-shaped hollow scooped out by the accumulation and movement of a mountain glacier at its head. A drumlin is an elongated, streamlined hill composed of glacial till shaped by the movement of ice sheets. An esker is a long, winding ridge of stratified sand and gravel deposited by meltwater streams flowing within or beneath stagnant glacial ice.
