input: Please answer the following: - Acid rain leaches aluminum from clay particles in soil - Aluminum flows into streams and lakes - Acid rain dissolves minerals and nutrients in soil - Washes them away so plants can't benefit from them - PH in soil and water gets affected which can kill plants and animals What might be the last step of the process?
++++++++++
output: Acid rain in fog at higher elevations can strip foliage off trees.
Please answer this: - 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?
++++++++
Answer: The remaining carbon dioxide is expelled through the mouth.
Problem: - People breathe and expel carbon dioxide - Engines produce carbon dioxide - Living things produce waste - Waste decomposes - Decomposition produces methane - Water evaporates - Water vapor joins the atmosphere What might be the last step of the process?

A: Carbon dioxide, water vapor and methane are greenhouse gases
Problem: Given the question: - An organism dies - Water seeps into the remains - Minerals dissolved in the water form crystals - Crystalized minerals cause the remains to harden What might be the last step of the process?
++++++++++++++++++++++++++++++++
The answer is:
The minerals form a fossil.
input question: - A mine is excavated in the side of a mountain - Miners enter the mine - Miners remove the coal from the mine - The coal is placed into carts or on a conveyor belt - The coal is moved up to the surface - The coal is loaded onto a truck What might be the last step of the process????
output answer: The truck takes the coal to a power station.
input question: - You breathe air in - Air enters bronchial tubes - Air is then split into the bronchioles of each lung - Bronchioles have alveoli which are tiny air sacs - Alveoli is surrounded by many small blood vessels - Oxygen passes through alveoli into blood vessels - Blood leaves the lungs as it travels through the body - Blood carries carbon dioxide back to the lungs What might be the last step of the process????
output answer:
Carbon dioxide released when you exhale.
