which of the following best describes where fossil fuels come from?\ndecayed animals\nthe hardening of nitrogen oxides\ndecayed plant material\nthe merging of iron, lead, and zinc
Answer
Brief Explanations:
Fossil fuels are formed from the remains of ancient plants and animals that have been subjected to heat and pressure over millions of years. The main source is decayed plant material which undergoes a long - term transformation process. Decayed animals contribute less compared to plants. Nitrogen oxides hardening and the merging of iron, lead, and zinc have nothing to do with fossil - fuel formation.
Answer:
C. decayed plant material
