[Q]: What is the final step of the following process: - Plants and animals long ago died - They are buried under layers of soil - Pressure builds over time - The remains liquefy
****
[A]: The carbon atoms rearrange to become a new substance.

input: Please answer the following: What is the final step of the following process: - You breathe in - Air goes through all the little branches in your lungs to fill up the air sacs, or alveoli - Oxygen goes through the walls of the alveoli and into the capillaries - The oxygen goes into the bloodstream - Oxygen is left and carbon dioxide is picked up
++++++++++
output: You breathe it out through your lungs

Please answer this: What is the final step of the following process: - Water from the ocean washes onto beaches in waves - The waves contain sediment from the ocean - The water and particles in it hit rocks and sand on the beach - The wind and current sometimes push the water and particles harder - Tiny parts of the rocks on the shore come off the larger rocks - The waves pick up sand and small rocks from the beach - The waves go back out into the ocean - The waves carry the new particles with them

Answer: Rocks and the beach look a little different.

Problem: What is the final step of the following process: - 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

A: The ecosystem is out of balance, causing further problems

Problem: Given the question: What is the final step of the following process: - A person breathes in oxygen - The oxygen passes through the bronchial tubes to the lungs - The oxygen is moved into the bloodstream - Circulates through the body - The cells in the body exchange the oxygen with carbon dioxide - The bloodstream carries the carbon dioxide back to the lungs
++++++++++++++++++++++++++++++++
The answer is:
The lungs expel the carbon dioxide through the nose and mouth.

Problem: What is the final step of the following process: - 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

A:
It will turn into either petroleum or natural gas
