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 There are more clouds in the sky happens, how will it affect more heat rises from the ground. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: less

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. Question: suppose There are less plants that grow happens, how will it affect LESS sediment being transported. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: less

Process: - Skin is cut or damaged - Bacteria enters through the wound - The bacteria reproduces and spreads - Causes symptoms - The bacteria is either fought off or becomes a disease. Question: suppose dirty object caused wound happens, how will it affect more bacteria will spread. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: more

Process: - Build a satellite - Attach a rocket - Add rocket fuel - Launch rocket - Satellite goes into orbit. Question: suppose more rockets will be launched into space happens, how will it affect MORE or LARGER satelites in space. How does the supposed perturbation influence the second effect mentioned. Answer by more, less or no effect
Ans: more
