Answer:

  • As this less than 2 mm in diameter, with an appearance of dust or sand.
  • These pyroclasts are commonly pea to walnut sized.
  • Lapilli, or cinders, range from 2 mm to 64 mm in diameter.
  • 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.
