Which process prevents lava dome collapse during cooling?

💡 Explanation

Crystallization heat of fusion controls cooling rate fluctuations; because liquid to solid releases energy this stabilizes the dome’s temperature. Therefore, large temperature differences are avoided, rather than the effects of convection, conduction or advection.
