Question: 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. Perturbation hypothesis: suppose More greenhouse gases are produced happens, how will it affect Temperature of the earth decreases. Does the supposed perturbation have an effect (direct or indirect) on the process?
Answer: yes

Question: Process: - The sun gives off radiation - The radiation is aborbed by the Earth - Some of the radiation goes back into space - Some is trapped by the atmosphere - If too much heat is trapped - Global warming occurs. Perturbation hypothesis: suppose seeds that do sprout do not survive because of lack of nutrients or water happens, how will it affect More radiation is absorbed by the earth. Does the supposed perturbation have an effect (direct or indirect) on the process?
Answer: no

Question: Process: - The carafe is filled with water - The water is poured into the machine at the back - Coffee beans are put into a grinder - The grinder is activated - A filter is put into the coffee maker - The ground coffee is put into the filter - Sometimes a bit of salt is added to the grounds to bring out flavor - The top of the machine is closed - The power is turned on - The water passes through the grounds and becomes coffee. Perturbation hypothesis: suppose an increase in the filter strength happens, how will it affect LESS coffee being made. Does the supposed perturbation have an effect (direct or indirect) on the process?
Answer:
yes
