When a volcano erupts explosively, it releases clouds of hot ash, gas, and pumice. In many cases these clouds, or portions of them, are too dense to rise and instead race down the slopes of the volcano.
The answer is Explosive . It is explosive because during a explosive eruption there are clouds of ash, gas , and rock , and with a pyroclastic flow there is dust and ash . there for the answer must be explosive .
an explosive volcano will usually have a pyroclastic flow
The name of the explosive outflow of gas from a volcaic eruption is a Pyroclastic Flow, however it can also be called a Pyroclastic Surge.
A pyroclastic flow of hot gases.
No. Pyroclastic flows are characteristic of explosive eruptions.
Pyroclastic flows occur during volcanic eruptions. They consist of a superheated mixture of volcanic ash, rock fragments, and gases that move rapidly down the flanks of a volcano at high speeds, causing significant destruction to everything in their path.
An explosive volcanic eruption. Pyroclastic flow is a mixture of fast flowing hot gases that travel down and away from the eruption.
Mount Etna has had both explosive and "quiet" eruptions and has produced lava flows, lava fountains, and pyroclastic flows.
Volcanoes formed by pyroclastic deposits are typically stratovolcanoes, also known as composite volcanoes. These volcanoes are characterized by their steep profiles and are formed from alternating layers of lava flows, ash, and volcanic rocks resulting from explosive eruptions. Notable examples include Mount St. Helens in the United States, Mount Fuji in Japan, and Vesuvius in Italy. The explosive nature of pyroclastic eruptions contributes to the formation of these complex volcanic structures.

Cinder cone volcanoes are made of pyroclastic material and most often form from moderately explosive eruptions.
