Process:  - Chemicals like sulfur dioxide and nitrogen are released into the air - These substances rise into the high atmosphere - They react with water and oxygen - This creates a more acidic rain - The rain with the high acid content falls.  Perturbation hypothesis: suppose The freezer is of insufficient size happens, how will it affect MORE damage by acid rain.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

Process:  - Bacteria enter the body - Bacteria start to divide and grow - The uncontrolled growth takes away resources from other cells - Other cells cannot function properly - We feel unwell - The growth and division of bacteria produce toxins - Toxins harm the body - The body tries to react to the toxins - The body&#x27;s natural defenses can sometimes cause us to feel unwell.  Perturbation hypothesis: suppose more frequent hand washing happens, how will it affect MORE SEVERE disease occurring.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process:  - Dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand - Over time, more sediment piles on top - The resulting heat and pressure transforms the organic layer into a dark and waxy substance known as kerogen - Left alone, the kerogen molecules eventually crack - The molecules break up into shorter and lighter molecules composed almost solely of carbon and hydrogen atoms - It will turn into either petroleum or natural gas -   Perturbation hypothesis: suppose more sediment will form happens, how will it affect LESS oil.  Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process:  - Sediment becomes loose from the rest of the soil - The sediment rolls down hill towards a river - The heavy items sink to the bottom - The lighter items float on the top and in convection cycles - As the river flows the sediment is moved - The sediment gets dumped through tributaries into lakes and the ocean - The sediment keeps moving around the world in convection currents.  Perturbation hypothesis: suppose there is more water from the tap happens, how will it affect more water available.  Does the supposed perturbation have an effect (direct or indirect) on the process?
