A) explain the difference between combined cycle and cogeneration. (10 points)

b) explain the significance of proximate and ultimate analysis from engineering (utilization) standpoint (15 points)

c) explain in your own words clearly how fossil fuels have formed in nature (type written) using your own sketch of global carbon cycle diagram. what are the major differences in composition between coal, oil and natural gas what is the difference in raw constituents that make oil, gas and coal? (15 points).

Earthquakes and tsunamis

The reason why i feel that the theory of plate tectonics is correct because scientists have found dinosaur bones of the same species in africa, asia, and in the americas. which means that they must have been together at one point in time. plate tectonics is also how the hawaiian islands were formed. as the plate hawaii is on was moving north west, magma would melt through the sea bottom and hardening. forming into the island chain. plate tectonics also explains the mariana trench. two plates were moving away from each other and made a giant crack in the ocean floor running 2,550 kilometers (1,500 miles)  long.

This is a true statement  hope this : )

I'm pretty sure that the answer is c.
