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 not enough milk and water is susbstituted for the milk happens, how will it affect less sediment gets dumped into tributaries. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

Process: - Waves hit the coast - Waves have energy that pushes the water and sediment - The sediment can help erode land like sandpaper - Water washes the sediment back - Some sediment is left as sand. Perturbation hypothesis: suppose the child has a hormonal disease happens, how will it affect more waves hit the coast. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

Process: - Air is drawn in through the mouth - The air goes down the esophagus - The air moves into the lungs - The carbon dioxide is removed - The remaining oxygen enters the body - The remaining carbon dioxide is expelled through the mouth. Perturbation hypothesis: suppose less carbon dioxide is removed from the air happens, how will it affect LESS oxygen being brought to the body. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - A fuel is heated in an oven - Above the oven is a tank of water that is sealed - The tank of water begins to boil above the oven - A the water boils steam is created - The steam is denser than air so it needs a place to go - The steam is forced out of the tank and into a piston - The piston moves up - The valve of the piston closes - The valve on the next piston opens - The steam fills the next piston, driving it up, and the other one down - Perturbation hypothesis: suppose the oven is old happens, how will it affect LESS power produced by the steam engine. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes
