Please answer this: Process:  - The earth develops cracks deep beneath the surface - The cracks get very long and big in some places - The earth places pressure against the rocks on both sides of the cracks - The pressure causes the rocks to press against each other very hard - The cracks continue to develop - The earth moves against itself on both sides of the cracks - The pressure and movement around the cracks causes the rocks to crumble in some places - A lot of energy is released - The energy causes seismic waves - The seismic waves move the earth in an earthquake.  Perturbation hypothesis: suppose less pressure around the cracks happens, how will it affect MORE/STRONGER earthquakes.  Does the supposed perturbation have an effect (direct or indirect) on the process?

Answer: yes


Please answer this: Process:  - A large rocky area is formed - The rocky area has a higher elevation than the surrounding areas - Water from precipitation falls in the area - The water forms a stream - The stream flows towards lower elevation - The stream becomes a river - The river continues to flow along the same path for a long time - The river erodes the rocky area that it touches - The eroded area cuts deeply into the rock.  Perturbation hypothesis: suppose there will be more waste in landfills happens, how will it affect MORE/LARGER valleys being formed.  Does the supposed perturbation have an effect (direct or indirect) on the process?
++++++++
Answer: no


Please answer this: Process:  - Coal is burned - Sulfur in the coal combines with oxygen to form sulfur oxides - The sulfur oxides are released into the atmosphere - The sulfides combine with oxygen in the atmosphere to form sulfur trioxide - The sulfur trioxide reacts with water in the atmosphere to form sulfuric acid, a very strong acid - The sulfuric acid makes the rain acidic -   Perturbation hypothesis: suppose more global warming causes drought happens, how will it affect more sulfer oxides are released into the atmosphere.  Does the supposed perturbation have an effect (direct or indirect) on the process?
