Process: - Greenhouse gases are released into the air by human activities - The earth changes energy from the sun into heat - Heat rises from the ground - Greenhouse gas molecules in the atmosphere prevent the heat from going into space - The temperature of the earth increases - The temperature continues to rise and melts the polar ice caps - The temperature rises even faster.  Question: suppose global economic recession forces plants to close happens, how will it affect a SMALLER greenhouse effect.  How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: more

Process: - Muscles work by expanding and contracting - A muscle fiber gets a signal from its nerve - Proteins and chemicals release energy to either contract the muscle or relax it - When the muscles contracts the bones connected to he muscle are pulled closer together - When the muscle relaxes the bones move farther apart.  Question: suppose the muscles receive more chemicals happens, how will it affect The muscles being pulled closer to the bones.  How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: more

Process: - Limestone is located under the soil - Rain picks up carbon dioxide as it falls to earth - The rain falls on the soil over the limestone - The carbon dioxide in the rain washes through the soil - The carbon dioxide turns into acid - The acid in the rain gets to the limestone below the soil - The acid dissolves the limestone - Acid continues to erode the limestone with more rain over time - The eroded limestone sometimes forms caves.  Question: suppose there is more rain happens, how will it affect LESS or SMALLER caverns.  How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: less

Process: - The air is cold - Water is in the air - The water forms tiny ice crystals - The ice crystals collide with each other - The ice crystals stick to each other - The ice crystals get bigger as more of them stick together - The ice crystals get too heavy to be in the air - The ice crystals become snowflakes - The snow flakes fall to the ground as snow.  Question: suppose more aluminum reaches the waterways happens, how will it affect more ice crystals get heavy.  How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect

Ans: no effect
