it sets fire to it and everything explodes
It's continuously processed in the nitrogen cycle. In broad outline nitrogen in the atmosphere is fixed by bacteria so that it's available to plants making protein. This protein is consumed by animals and plants or returned to the atmosphere as methane. The plant nitrogen is converted to animal protein which is eventually returned to the atmosphere by bacteria. For more detail you might wish to refer to information on wikipedia.
Is that "1 mole of nitrogen" could be interpreted as one mole of nitrogen atoms or a mole of nitrogen molecules.
I think it might be the chemical formula for 1 oxygen and 2 nitrogen
smoking weed does not affect your period, smoking grass might however
Combustion (the burning of something) releases chemical energy stored in the fuel, whatever it is. The fuel might be wood, coal, oil or petroleum fuel, or something else like that. But whatever the fuel is, we burn it, generally to create heat (thermal energy). This thermal energy is used as we wish. We might convert it to mechanical energy to move a vehicle, or something like that.
how might a modern farming speeding up the decomposition of matter in soil affect the nitrogen cycle
Human Activities affect the carbon cycle at a huge rate. Release of toxins and other waste might alter the cycle.
If we had no precipitation plants might not grow.
because it takes away most of it`s habitat
The source of nitrogen oxides (NO and NO2) is essentially the combustion of fossil fuels and derivatives. Also some chemical processes release nitrogen oxides. As an addenda, the questioner might be seeking to know if nitrogen compounds are formed in other ways, to which I would suggest that virtually all PLANTS make nitrogen compounds by extracting and combining atmospheric and soil-bound elements. I hope that helps.
Rocks and the Rock Cycle. ROCKS: Rocks, rocks, rocks. Weathering is all about rocks.
All life will completely stop as well as the cycles that these used.
Ice in glaciers will melt and more water will move into the air
If the Earth did not have oceans, there would be far fewer sedimentary rocks. This would make the entire rock cycle slower.
Food grade nitrogen doesn't have any contaminants in it; regular nitrogen might.
Ignition might work.
