Which phenomenon restricts deep water renewal within silled fjords?

💡 Explanation

Density stratification prevents deep water renewal because restricted vertical mixing occurs due to density differences; new water cannot easily displace older, denser water below the sill, therefore water becomes stagnant rather than well-flushed as in open ocean conditions.
