Which eruption risk increases as rhyolitic lava cools rapidly forming a dome?

💡 Explanation

Rapidly cooled rhyolitic lava in domes leads to increased pressure; degassing is impeded. Therefore, the risk of violent explosions increase because volatile gases are trapped during solidification, leading to over-pressurization rather than stable flow.
