Respuesta :

A mixture of air, hot ash, and pumice lapilli that rushes down the side of a volcano in a scalding avalanche is termed a(n) pyroclastic flow.

Pyroclastic flows are all secretions combined with robust materials and gases. The speed of pyroclastic flows on the number of solids and gases. A characteristic of pyroclastic flows is that they can produce a high degree of destruction when they erupt.A pyroclastic flow is a dense, fast-moving flow of solidified lava pieces, volcanic ash, and hot gases. It occurs as part of certain volcanic eruptions. A pyroclastic flow is extremely hot, burning anything in its path.

Exploding gas bubbles shatter the pumice into tiny fragments which we call volcanic ash. Ash clouds are driven high into the atmosphere by the force of these eruptions; the finest particles may spread for hundreds of miles before falling back to Earth.
