Why may a fjord have a shallow sill and a deeper inner basin?
Answer and explanation
Correct answer: The main glacier overdeepened the inner part and a deposit or resistant threshold remained near the mouth
A fjord occupies a glacially excavated valley that has later been flooded by the sea. Ice may erode the inner basin more intensely, producing great depth, while weaker erosion, resistant bedrock, or terminal deposits near the mouth leave a shallow sill. Loess, karst dissolution, and barchan dunes do not explain this characteristic cross-profile.
