Answer:
high temperature and high pressure
Explanation:
Coal is one of the solid minerals found underground. Coal is believed to have been formed from vegetation during the carboniferous era. The decomposition of these materials under pressure in the absence of air led to the formation of coal.
In the process of carbonization, the vegetation was converted in stages to peat, lignite, bituminous coal and anthracite.
The formation of anthracite is favored by high temperature and high pressure underground.
Substinence farming is farming food that is just enough to live off of. You don't sell substinence crops.

Well, when the wind blows, it picks up dirt and dust. Gravity makes that dirt and dust fall down. Eventually, builds up landforms! And pressure from gravity may push down and compact ground, soit changes that way.
I hope this helped!
