[Q]: 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 less sediment gets dumped into lakes happens, how will it affect LESS sediment being transported. Does the supposed perturbation have an effect (direct or indirect) on the process?
****
[A]: yes

[Q]: 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 smaller fault lines happens, how will it affect MORE/STRONGER earthquakes. Does the supposed perturbation have an effect (direct or indirect) on the process?
****
[A]: yes

[Q]: Process: - A forest fire starts - The trees and plants burn - The animals lose their homes - If the animals can not escape, they may die from smoke inhalation - The plants that provide food are gone - The animals have little to eat - Perturbation hypothesis: suppose people build more hydro electric plants happens, how will it affect animal is unprotected in environment. Does the supposed perturbation have an effect (direct or indirect) on the process?
****
[A]: no

[Q]: Process: - Oxygen enters the body through the mouth or nose - The oxygen travels into the lungs - The oxygen binds to hemoglobin proteins within erythrocytes (red blood cells) - The erythrocytes are pumped through the body by the heart - All cells receive the oxygen. Perturbation hypothesis: suppose government intervention has stopped the causes of acidic rain happens, how will it affect more oxygen enters the body. Does the supposed perturbation have an effect (direct or indirect) on the process?

[A]:
no
