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
Problem: Given the question: - Acid rain makes waters acidic - Causes them to absorb aluminum from soil - The water runs off from the soil into lakes, streams, etc - Fish and their eggs die - Frogs and plants die - Insects and other wildlife die What might be the last step of the process?

input question: - Items are collected - The items are sorted - Trash is removed from everything else - Goes to a landfill - The items go into a baler machine for each kind of material - They come out as bales What might be the last step of the process????
output answer: The bales are shipped to manufacturers to use to make products.
- The consumer throws aluminum cans and foil into a recycle bin - The aluminum is collected - Taken to a treatment plant - The aluminum is sorted and cleaned ready for reprocessing - The aluminum is re-melted - Turned into molten aluminum - The aluminum is made into large blocks called ingots - The ingots are sent to mills to be rolled out What might be the last step of the process?
----
Answer: The rolled out product is made into new aluminum products.
Q: - Air is drawn in through the mouth - The air goes down the esophagus - The air moves into the lungs - The carbon dioxide is removed - The remaining oxygen enters the body What might be the last step of the process?
A: The remaining carbon dioxide is expelled through the mouth.
[Q]: - Magma rises from deep in the earth - The magma goes into volcanos - The volcanos pressure the magma upwards - The pressure causes the magma to push through the surface of the volcano - The lava cools - The lava forms new rock - New magma is pressured to the surface of the volcano What might be the last step of the process?
****
[A]:
The volcano bursts through the rock the formed after the last eruption.
