Which outcome occurs when unconfined pyroclastic flows rapidly decelerate?

💡 Explanation

Ignimbrite forms because rapid pyroclastic flow deceleration promotes particle settling and agglutination, generating extensive sheets. Therefore, ignimbrite deposition ensues, rather than increased albedo or edifice collapse, because internal flow dynamics change not atmospheric composition or vent stability.
