Which of the following describes a 'Kame' in glacial geomorphology?
A. A steep-sided, irregular mound of stratified sand and gravel deposited by meltwater streams on the surface or at the snout of a stagnant glacier✓ Correct Answer
B. A long, winding ridge of stratified drift deposited by meltwater tunnels beneath glacial ice
C. An isolated bedrock knob or hill protruding prominently above a glaciated lowland or ice sheet
D. A horseshoe-shaped amphitheater-like depression carved into a mountain headwall by glacial erosion
💡 Solution & Explanation
A kame is defined as a steep-sided, irregular mound composed of stratified sand and gravel that forms when glacial meltwater deposits sediment within depressions on stagnant or retreating ice sheets. Long winding ridges of stratified drift refer instead to eskers, while horseshoe-shaped mountain depressions carved by glaciers are known as cirques. These depositional landforms provide crucial geological evidence regarding the extent and behavior of past glacial movements.
