Which outcome occurs when pyroclastic flow loses momentum?

💡 Explanation

Ignimbrite sheet deposition results from the momentum loss causing particle settling via gravitational sorting, because the Froude number decreases towards zero. Therefore, the heavy particulate matter accumulates, rather than ash cloud formation or mudflow changes which require ongoing force.
