Which outcome occurs when pyroclastic flows deposit volcanic material?

💡 Explanation

Deposition of pyroclastic flows frequently leads to the consolidation and welding of volcanic ash and rock fragments into ignimbrite sheets because the high heat encourages sintering which fuses them together. Therefore ignimbrite formations occur, rather than enhanced weathering, thermal energy or ozone reduction which do not directly result.
