Process: - Gases cause pressure beneath the earth - The gases come to a head and push molten magma to the surface - The magma cools - With enough time the pressure builds up greatly - The resulting volcano may explode. Perturbation hypothesis: suppose there is movement with tectonic plates happens, how will it affect magma is pushed with pressure to cool. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - People dig up coal from the ground - People burn coal for heat or electricity - Pollution from the coal goes into the sky - Coal pollution enters clouds - Clouds rain over an area - The polluted rain becomes acid rain. Perturbation hypothesis: suppose there is more rain happens, how will it affect more coal is burned. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

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 more tachycardia happens, how will it affect HURTING the animal to hibernate properly. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - Bread is exposed to the elements - Bread absorbs water from the air - Bread absorbs warmth from the air - Dust particles with mold spores fall on bread - Mold spores start to consume the bread for energy - Mold colonies grow until they are visible. Perturbation hypothesis: suppose more mycelium grows happens, how will it affect MORE mold forming on bread. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no
