What is the primary geomorphic process responsible for the formation of fjords?
A. Marine wave erosion along drowned river valleys
B. Glacial erosion of deep U-shaped valleys subsequently flooded by the sea✓ Correct Answer
C. Wind deflation in hyper-arid coastal deserts
D. Tectonic subsidence along active transform fault lines
💡 Solution & Explanation
Fjords are created through glacial erosion where deep U-shaped valleys are carved out by moving ice sheets and subsequently inundated by rising sea levels. Marine wave erosion and wind deflation shape entirely different coastal and desert landforms rather than steep-walled coastal troughs. Geomorphology questions focusing on glacial landforms frequently appear in physical geography assessments.
