derived from algae trap beneath earth layers, forming crude oil

55
Q

hydrocarbons and methane, trapped beneath seabed surface from anaerobic organisms

A

natural gas

56
Q

2 factors affecting fossil formation

A
  1. absence of decomposers
  2. soil quality
57
Q

energy from organic remains is trapped beneath earth, affecting fossil formation

A

absence of decomposers

58
Q

clay soils help prevent decomposers from interacting with organic remains; prevents oxygen to oxidize with the organic material

loose soils allows moisture, microorganisms, and O to alter and decompose organic materials

A

soil quality
