[Q]: - The organism must die to begin the process - The soft tissue decomposes - The bones are left behind - Scavengers tear the body apart and move the bones elsewhere - Wind and rain also scatter the bones further - The bones left behind will weather and become buried by sand and soil - The proteins in the bone are replaced with minerals that are dissolved in the soil - This creates a rock-like substance called a fossil - Water and wind erosion wear away the layers of soil on top of the fossil What might be the last step of the process?
****
[A]: This makes discovery of the fossil possible.
input: Please answer the following: - Animals and plants die in soft soil or mud - Sediment builds up over the remains - The remains decompose, leaving only trace amounts - The remaining parts over the years are replaced with mineral What might be the last step of the process?
++++++++++
output: A fossil is formed
Please answer this: - Coal is loaded into the firebox - The boiler produces steam under high pressure - The steam generated in the boiler flows down into a cylinder - Just ahead of the wheels, pushing a tight-fitting plunger, the piston - The piston is connected to one or more of the locomotive's wheels through a kind of arm-elbow-shoulder joint called a crank and connecting rod - As the piston pushes, the crank and connecting rod turn the locomotive's wheels and power the train along What might be the last step of the process?
++++++++
Answer: An outlet valve opens and the piston pushes the steam back through the cylinder and out up the locomotive's chimney
Problem: - A bird lays an egg - The egg hatches into a baby bird - Baby bird eats - Grows into an adult bird - The bird finds a mate - The pair build a nest What might be the last step of the process?

A: The birds lay eggs.
Problem: Given the question: - Wind and water erode rocks - The wind and water pick up sediment that came off the rocks - Sediment is carried to an area by the wind, water, air, or ice - Sediment is deposited on the same spot many times - The sediment piles on top of other sediment for a long time - The sediment near the bottom is compressed by the weight of newer sediment What might be the last step of the process?
++++++++++++++++++++++++++++++++
The answer is:
The sediment becomes sedimentary rock as it is pushed together by the heavy weight
Problem: - Dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand - Over time, more sediment piles on top - The resulting heat and pressure transforms the organic layer into a dark and waxy substance known as kerogen - Left alone, the kerogen molecules eventually crack - The molecules break up into shorter and lighter molecules composed almost solely of carbon and hydrogen atoms What might be the last step of the process?

A:
It will turn into either petroleum or natural gas
