Pyroclastic material! Save
Ashfall is the common name given to the ash rocks and other debris that is ejected from a volcano during an eruption.
Tephra.. (not pumice - Pumice is the light stone which forms during an eruption)
I think it's igneous rock
Lapilli--Lapilli is pyroclastics the size of walnuts.Cinders-- Cinders are a type of pyroclastic material the size of a pea. According to the text, Earth An Introduction to Physical Geology, Cinders come in different forms when "ejected lava blobs are pulverized by the escaping gases".Blocks-- Blocks are particles larger than Lapilli's and are formed by harden lava.Bombs-- Bombs too help to produce blocks, but they are ejected as lava. They take on an streamline shape. They usually tend to fall on the slopes of a cone volcano and they can be ejected far from the volcano due to the force of escaping gasesI answered this earlier but this is a better answer ;)
When a volcano erupts, the earth is opened up to produce lava, which is magma that has reached the surface. Sometimes, there are materials, or fragments, that are ejected from the volcano by the force of the volcano erupting. These blobs of lava are called Pyroclastic material.

These sorts of ejecta are sometimes called 'bombs'.

The matter thrown out of a volcano while it is erupting is called lava, and it consists of melted rock matter. Before erupting, the lava moves underground towards the opening of the volcano. When it is underground like this, it is called magma.
The Volcano has a huge structure below it. The molten rock deep within it is called Magma. A subsidiary volcano may form from the main body, this is called a Parasitic cone. Some times some volcanic materials may seep out near the volcano, this opening is called Vent. The molten rock erupting from the Volcano is called Lava. The mouth of the volcano is called Crater. The highest point of a volcanic mountain is called Summit while the underground passage of magma is called Conduit. The Channel through which lava is ejected out is called the Throat. Ash or fragments of rocks and lava are what is blasted out forming Ash clouds due to the explosion
