Which consequence results when pyroclastic flows erode unstable terrain?

💡 Explanation

Increased lahar occurrence happens because erosion by pyroclastic flows can destabilize slopes, releasing sediment and water. This triggers mudflows involving sediment; therefore, lahars are more frequent, rather than producing obsidian, melting ice or increasing albedo without adding particulates.
