Problem: Process: - Plants start growing on or near the rocks - The roots of the growing plants start to break up the rock - The plant acids dissolve the rock - The rock is broken down into smaller pieces - Erosion begins. Perturbation hypothesis: suppose Less carbon causes less acid rain happens, how will it affect more rock is broken down. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: 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 there is more wind happens, how will it affect LESS erosion by the ocean. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: Process: - Owls have specially adapted eyes that see better at night - Owls sit at high points in trees and look around - When an owl spots a rodent they track it - When the rodent is standing still the owl swoops down - The owl grabs the rodent with their tallons - The owl uses their beak to eat the rodent. Perturbation hypothesis: suppose the liver is defective happens, how will it affect there are fewer owls. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: no

Problem: Process: - An isotope has too many protons - The isotope is unstable - The isotope emits radiation - The isotope decays - The isotope loses some atomic particles - The isotope turns into a different element - The isotope is finished decaying and emitting radiation. Perturbation hypothesis: suppose the isotope becomes more stable happens, how will it affect the isotope woud emit more radiation. Does the supposed perturbation have an effect (direct or indirect) on the process?

A:
yes
