How does an explosive eruption produce pyroclastic flow?

I think this must be if i remember The huge amounts of smoke and ash often seen billowing from active volcanoes generally travel vertically, carried upward by the powerful thermal updrafts volcanoes generate. There are two major types of pyroclastic flows. The first actually comes from the collapse of one of the typical columns of smoke and ash from a volcano. This is the fastest and most energetic type, caused when the weight of the material in the column is too much for the air pressure to support.

The other type of pyroclastic flow is caused by the collapse of a lava dome, the swelling of the earth caused by pressure from magma below. This pyroclastic flow actually has two major components, the visible ash cloud along with an avalanche of hot blocks from the disintegrating dome. The two types of flows leave different types of ash deposits, which geologists can identify long after an eruption.

This is the photoelectric effect, and it is best explained by the particle model of light.

<h3>What is the photoelectric effect?</h3>

The photoelectric effect refers to the emission of negatively charged particles and electromagnetic radiation that hits an object.

The photoelectric effect shows how electrons can be released from a given object when this material is absorbing electromagnetic radiation.

The photoelectric effect is a fundamental piece of evidence for understanding the nature of light particles.
