They differ in size and origin. Volcanic ash consists of fine material ejected by a volcano up to 2 mm (0.08 in) in diameter. Lapilli consists of larger material, ranging from 2mm to 64 mm (2.52 in) in diameter. Blocks and bombs are larger than 64 mm. Volcanic bombs form when molten lava is ejected during an eruption and solidifies in the air. A volcanic block is from material that is already solid when it is ejected, coming either from country rock or rock formed by previous eruptions.
volcanic ash is made up of rock fragments less than 2 millimeters in diameter, volcanic bombs are large fragments.
Bombs are molten rock, blocks are solid rocks. Both must measure over 64 mm (2.5in).
Bombs are a type of pyroclastic debris
yes
Volcanic ash, cinders, and bombs are called tephra.
A volcanic mountain made up of volcanic ash, cinders, and bombs is called a Cinder Cone Volcano.

Vocanic dust is Fine vocanic ash that is under .063 millimeters. Vocanic ash is tiny parts of rock or glass, its size is under 2 millimeters. Volcanic bombs are magma that bursts out of the volcano and harden in the air. There size is over 64 millimeters. Vocanic cinders are dark glassy fragments that are produced by gas in the vocano.

Volcanic bombs shoot out of the main vent because of the amount of ash.
Lava is a hot liquid from the inside of the earth and ash is a lava powder, which is very hot.
