Pyroclasts are single fragments that are produced following a volcanic eruptions where there expanding gases rapidly erupt resulting in either the fragmentation or obliteration of rock and magma. Fine-grained pyroclastic material is generally made from ash cause by extremely high fragmentation of rock or magma.

Why is my car shrinking?
Is the temperature falling where you are ? Metal will expand and contract in relation to temperature. You would need a very big pair of vernier calipers to measure your car accurately though. If it is shrinking about .025mm per 10 degrees drop in temperature then this may be normal. :) Could it be that you are getting heavier?
What is the volume of a cloud?
The mass and volume of an electron cloud would depend 100% on knowing the mass and volume of an electron, or a proton/neutron. Obviously, I don't know, because I was asking a question on what the mass and volume of a proton/electron was.
What is the full form of IRG?
Tape storage is primarily used for archival storage. The recording medium is a thin polyester tape between 0.38cm and 2.54cm wide, about .025mm thick and coated with magnetic particles. The tape is wound on wheels of various sizes. Data is recorded sequentially, one byte after the other, from the beginning of the tape to its end. Access times for tape storage are much slower than for floppy diskettes or hard disks.The following diagram shows how data is stored on the disk. The read/write head is comprised of several tracks, 9 tracks being very common. This means nine bits are recorded across the width of the tape simultaneously. Using nine tracks, one byte of data plus a parity bit is recorded at a time (vertically). Characters are grouped together to form a record (often called a block). Each record is separated from the next record by a blank inter-record gap (IBG). Each record is preceded by a header field. The IBG allows the software to position the tape for recording or playing at specific record numbers. Physical markers are used to indicate the ends of the tape, and may be metallic foil, clear plastic or software markers encoded on the tape. Software encoding uses BOT(beginning of tape) and EOT (end of tape) indicators. IRG=IBG
