Question: Process:  - Iron is exposed to oxygen - Is exposed to air - A chemical reaction occurs - The iron starts to oxidize - The iron starts to rust.  suppose rocks stay in one place happens, how will it affect MORE rust forming.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process
Answer: not impacting any step of the process

Question: Process:  - Sediment settles in a place due to gravity - The sediment breaks down into small particles - Wind or water picks up the sediment - The sediment travels along the same route as the wind or water - The sediment is deposited at new locations by the wind or water - The sediment is picked up again by new wind or water - The sediment travels further - The sediment is deposited again in a new place.  suppose there were less storms than usual happens, how will it affect the sediment would take longer to be deposited.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process
Answer: indirectly impacting a step of the process

Question: Process:  - A mold spore floats through the air - The spore lands on a piece of bread - The spore grows hyphae into the bread - The mold forms a colony - Sporangiophores grow upward - The mold sends out spores.  suppose the thermostat is not working correctly happens, how will it affect MORE mold forming on bread.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process
