input: Please answer the following: - Water gets into cracks in rocks - The water freezes into ice - The cracks expand - Over time the rocks split What might be the last step of the process?
++++++++++
output: The rocks are now in smaller pieces.
Please answer this: - Items that can be reused are placed into recycling containers - Recycling trucks pick up the items that are able to be reused - The recyclable items travel to a recycling plant - The items are sorted by what they are made of - The items are broken down into small parts - The small parts are melted to make new raw parts What might be the last step of the process?
++++++++
Answer: The raw parts are sold to manufactures to make new items.
Problem: - One type of air pollution is the addition of carbon dioxide gas into the air - Some scientists believe that releasing too much carbon dioxide into the atmosphere is one of the causes of global warming - This upsets the balance of the carbon cycle - The ozone layer helps protect us from harmful rays from the sun - It is getting damaged from air pollution such as methane gas from livestock and CFCs from spray cans - Acid rain is created when gasses such as sulfur dioxide get high into the atmosphere - The wind can blow these gasses for miles and then they get washed out of the air when it rains What might be the last step of the process?

A: This rain is called acid rain and can damage forests and kill fish.
Problem: Given the question: - Carbon dioxide passes through stomata in the leaves - Water is absorbed through roots - Chloroplast cells in leaves contain chlorophyll - Chlorophyll absorbs energy from sunlight - Energy splits water molecules into hydrogen and oxygen - Oxygen gets released into atmosphere - Hydrogen and carbon dioxide used to create glucose What might be the last step of the process?
++++++++++++++++++++++++++++++++
The answer is:
Glucose is food for plants.
input question: - Several types of gases form in the atmosphere - May come from different sources - The gases remain trapped in the atmosphere - Through the suns light the gases hold in heat and energy - Trap them in our atmosphere What might be the last step of the process????
output answer: The earth may become warmer this way.
input question: - Sunlight passes through the glass into the greenhouse - The plants and floor absorb the the sunlight - The absorbed sunlight is converted to heat - The heat cannot escape the glass - The heat is trapped in the greenhouse - The hot air rises - The colder air at the top is pushed to the bottom What might be the last step of the process????
output answer:
The colder air is then warmed by the floor and the plants.
