Which effect does crustal thickening have on volcanism?

💡 Explanation

Crustal thickening compresses mantle material, increasing pressure and volatile content beneath subduction zones, triggering increased explosive volcanism via flux melting, because volatile release lowers melting points. Therefore, the potential for stratovolcano eruptions notably increases, rather than other volcanic settings.
