How is a fjord formed?
Answer and explanation
Correct answer: By submergence of a glacial U-shaped valley by sea water
A fjord forms through two linked processes. First, a valley glacier erodes a deep, steep-sided U-shaped valley, often below present sea level. Later, rising sea level or subsidence of the coast allows seawater to flood that glacial trough. The result is a long, narrow, deep inlet with steep sides, so option C is correct. Delta erosion, limestone-cave collapse, and dune formation do not combine glacial excavation with marine submergence.
