Are my answers correct??
I just took the test its b and c
thank you for the answer
Thx c
everyone is correct, post all answers when finished
#1 [coal] sediment, rock and water apply pressure and heat, formed at the bottoms of swamps, oxygen cant reach the decaying matter
[oil] sediment, rock and water apply pressure and heat, formed at the bottom of oceans, oxygen cant reach the decaying matter
[natural gas] sediment, rock and water apply pressure and heat, formed at the bottom of oceans, oxygen cant reach the decaying matter, carbon bonds break to produce methane
#2 [crude oil] through drilling wells
[coal] through surface and underground mining
[natural gas] through drilling wells & through hydraulic fracturing
#3 C it was formed from ancient plants and animal remains
