Pyroclastic material is ejected from a volcano during an explosive eruption. These fragments are defined by their size, which ranges from less than 2 mm to greater than 64 mm.

Ashis less than 2 mm in diameter, with an appearance of dust or sand.
Lapilli, or cinders, range from 2 mm to 64 mm in diameter. These pyroclasts are commonly pea to walnut sized. Blocksand bombsrepresent the largest fragments, which are greater than 64 mm.
Blocksare erupted as hardened lava with a mostly angular shape, while bombsaresemi-molten and develop a streamlined-shape while flying through the air. HelpReset

Blocks And bombs represent the largest fragments, which are greater than 64 mm. Blocks are erupted as hardened lava with a mostly angular shape, while bombs semi-molten and develop a streamlined-shape while flying through the air.

Explanation:

A pyroclastic material is a particle ranges for the 2 to 64 mm in diameters and they can range of the volcanic bombs to the ash and the lavas.Like Lapilli or the cinders, they have a diameter of about 64 mm. They extend to miles form the volcano when they blast as blocks and can devastate lands, life, and property within there paths.
