Question 1: This trapped atmospheric carbon in the ground in immense peat________ that eventually were covered over and deeply buried by sediments under which they metamorphosed into coal.
Coal fired power plants provide 49% of consumed electricity in the United States. This is the Castle Gate Plant near Helper, Utah.
Believed approximate position of the proto-continents toward the end of the Carboniferous period; the light blue represents shallow seas where many of today's coal deposits are found, as opposed to deeper waters which gave rise to oil-bearing rocks derived from marine species. The ice caps were known to be very large, lowering sea levels extensively by locking up oceanic waters into solid ice, though how large the ice caps became is a matter of debate.
