Soot is often produced when burning wood.
ash? soot carbon
yes, from the rocks falling or the lava burning them or the big black smoke that comes after the eruption
82% comes from coal burning. Hope that helps!
The black gunk that comes out of the exhaust pipe when starting the car is probably carbon buildup within the exhaust system. Carbon buildup happens when the engine is not burning fuel as efficiently as it can.
If its black smoke you are burning oil possibly due to oil getting in your exhaust by tilting the lawnmower on its side or your rings are allowing oil by.
