Which outcome results in volcanic islands when pyroclastic density currents interact with seawater?

💡 Explanation

Pyroclastic flows entering seawater result in rapid cooling and **consolidation**, forming **tuff cones**. This occurs because the pyroclastic material agglutinates before being fully dispersed. Therefore consolidation creates a stable structure, rather than dispersion of material.
