Which risk increases when low-silica lava cools rapidly?

💡 Explanation

The risk of forming glassy rock increases due to rapid cooling preventing crystal formation; this is vitrification. Because the lava’s atoms freeze in a disordered state rather than developing mineral structures, aa lava requires slower crystallization and viscosity, therefore these alternatives are not as favoured.
