Process:  - Fault lines appear underground - The fault lines grow over time - The rocks on each side of the fault lines rub against the rocks on the other side of the fault line - The rocks put pressure on each other - The rocks break from the pressure - The breaking of the rocks releases a lot of energy - The energy causes seismic waves - The seismic waves make the earth shake.  Perturbation hypothesis: suppose less rocks being available happens, how will it affect larger seismic waves.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Answer: yes


Process:  - Ocean waves hit land - Ocean water pulls sand off of beaches - Ocean water breaks rocks off of cliffs - Ocean water carries sand and rocks into the ocean - Sand and rocks go to other land or the bottom of the ocean.  Perturbation hypothesis: suppose more greenhouse gas molecules are in the atmosphere happens, how will it affect more ocean water breaks tocks off of cliffs.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Answer: no


Process:  - The blood sugar drops in a body - Cells in the pancrease release glucagon - The liver in response turns the glucagon into glucose - And releases it into the blood - The blood sugar levels are restored.  Perturbation hypothesis: suppose a person eats sweeter food happens, how will it affect less glucagon in liver.  Does the supposed perturbation have an effect (direct or indirect) on the process?
