Which limit maximizes silica-rich lava dome collapse frequency?

💡 Explanation

Magma cooling maximizes collapse frequency because thermal contraction during solidification increases stress until brittle failure via spallation occurs; therefore surface fragments break, rather than remaining stable due to alternative ductile deformation processes.
