Process: - 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 - The sediment becomes sedimentary rock as it is pushed together by the heavy weight - Question: suppose More sediment and formed more sedimentary rock happens, how will it affect less rock is deposited. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: more

Process: - Acid rain flows through soil - Chemicals from the acid rain kill plants and trees - The acid rainwater flows into rivers and streams - The chemicals kill fish - The chemicals kill animals that drink the water - Nitrogen builds up - Nitrogen destroys fish and shellfish populations. Question: suppose the person will find it harder to breathe happens, how will it affect LESS damage by acid rain. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: no effect

Process: - A can is thrown away into a recycling bin - The can is taken to a recycling center - Melted down along with other cans - The melted metal is turned into bars - Becomes material for other products. Question: suppose more cans are taken to a recycling center happens, how will it affect LESS aluminum cans being recycled. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: less

Process: - Greenhouse gases are released into the air by human activities - The earth changes energy from the sun into heat - Heat rises from the ground - Greenhouse gas molecules in the atmosphere prevent the heat from going into space - The temperature of the earth increases - The temperature continues to rise and melts the polar ice caps - The temperature rises even faster. Question: suppose people use public transportation less happens, how will it affect less heat rises from the ground. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: less
