Q: Process: - Iron is exposed to oxygen - Is exposed to air - A chemical reaction occurs - The iron starts to oxidize - The iron starts to rust. Perturbation hypothesis: suppose oxygen is exposed to iron happens, how will it affect MORE rust forming. Does the supposed perturbation have an effect (direct or indirect) on the process?
A: yes

Q: Process: - Aluminium cans are put into a recycling bin - Aluminium cans are then collected and taken to a treatment plant - At the treatment plant the aluminium is sorted and cleaned - Readied for reprocessing - The aluminum cans go through a re-melt process - Turned into molten aluminium - The molten aluminum is made into large blocks called ingots - The ingots are sent to mills and are rolled out into thin sheets - The rolls are ready to be made into new aluminum products. Perturbation hypothesis: suppose less made into ingots happens, how will it affect more cans in recycling. Does the supposed perturbation have an effect (direct or indirect) on the process?
A: yes

Q: Process: - Water seeps into rocks - The water freezes and thaws - Cracks form in the rocks - Cracks also form when rocks heat up - The rocks slowly break down. Perturbation hypothesis: suppose it starts to snow happens, how will it affect LESS or SLOWER weathering occurring. Does the supposed perturbation have an effect (direct or indirect) on the process?
A: yes

Q: Process: - The animal eats large quantities of food that will be stored as fat - Winter comes and the animal finds a place to hibernate - Over a period of days, the animal's heart rate and breathing rate drop slowly - Electrical activity in the brain almost ceases completely, though some areas remain active - The animal has entered hibernation mode - Perturbation hypothesis: suppose the winter that comes is colder happens, how will it affect HURTING the animal to hibernate properly. Does the supposed perturbation have an effect (direct or indirect) on the process?
A:
yes
