Problem: Process:  - People breathe and expel carbon dioxide - Engines produce carbon dioxide - Living things produce waste - Waste decomposes - Decomposition produces methane - Water evaporates - Water vapor joins the atmosphere - Carbon dioxide, water vapor and methane are greenhouse gases -   suppose magma will burst through the rock formed by the last eruption happens, how will it affect LESS greenhouse gases.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: not impacting any step of the process


Problem: Process:  - You plant vegetable seeds in the ground - You water the seeds - You wait for the seeds to sprout - You keep the area free of pests and weeds while the plants grow - You thin out the plants as they get bigger to give them space to grow - You remove the vegetables from the plants when they are ripe.  suppose more seeds watered happens, how will it affect LESS vegetables.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: directly impacting a step of the process


Problem: Process:  - Gases cause pressure beneath the earth - The gases come to a head and push molten magma to the surface - The magma cools - With enough time the pressure builds up greatly - The resulting volcano may explode.  suppose isotope emits less radiation happens, how will it affect LESS or SMALLER eruptions.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A: not impacting any step of the process


Problem: Process:  - Fuel mixes with air - Mix gets inducted into cylinder - Piston compresses the mix - Spark plug emits a spark that ignites it causing combustion - Combustion gases expand - Pushes piston during power stroke - Exhaust valve opens to vent exhaust out tail pipe.  suppose the combustion gases do expand happens, how will it affect LESS power being generated by the engine.  Which of the following is the supposed perturbation?  - directly impacting a step of the process - indirectly impacting a step of the process - not impacting any step of the process

A:
