Which effect causes stratification in deep ocean layers?

💡 Explanation

Ocean water column layering arises because density gradients inhibit vertical mixing via salinity and thermal stratification; therefore, the stratification stabilizes the deeper layers, rather than the tidal mixing alone overcoming these density differences.
