products of volcanoes igneous rocks

There are various products from volcanoes not just lava as you may think.

products are:

. volcanic gasses - from the volcanoes these include sulphur and co2

. lava flows

. pyroclastic materials-  this happens when magma is forcefully or explosively ejected into the atmosphere as particles called pyroclasts .   these include ash blocks of magma and lapilli which are beetween 2mm and 64mm

where do you find pyroclasts? 

distabution by grain size - bombs and blocks of rock close to volcanoes and ash further away

distrabution by wind - the prevaling wind means the products of a volcanoe are mostly in that direction
