Which risk increases when rapidly cooling lava flows underground interact directly with icy permafrost?

💡 Explanation

Methane hydrate destabilization is more likely because the heat from the lava causes phase transition of the frozen methane into gas, a process known as thermal dissociation, rather than more direct cooling effects; therefore permafrost destabilizes promoting greenhouse gases.
