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. Perturbation hypothesis: suppose there is no liver in the body happens, how will it affect Less lighter items float to the top. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: no

Process: - Bees find a place for the hive, such as a rock crevice or tree branch - Bees gather nectar from flowers - The bees evaporate the nectar by passing it back and forth to each other - The evaporation turns the nectar into sugary honey - The bees chew the honey until it turns into moldable wax - The bees mold the wax into hexagonal (six sided) cylinders - Thousands of these hexagonal cylinders put together form the hive - Perturbation hypothesis: suppose humans leave the area alone happens, how will it affect a LARGER hive. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - Minerals fill spaces between bits of sediment - The sediments become glued together - The glued together parts become hard like cement - The sediment becomes a big rock - The rocks erode slowly - The rocks come apart - The rocks become smaller rocks - The rocks continue to erode into smaller rocks - The process starts again. Perturbation hypothesis: suppose animals take sediment away happens, how will it affect less rocks come apart. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes

Process: - Water in the clouds becomes very cold - The cold water forms ice crystals - The ice crystals grow by absorbing surrounding water droplets - Form snowflakes - The snowflakes fall to the ground. Perturbation hypothesis: suppose the clouds are colder happens, how will it affect more water in the clouds freezes. Does the supposed perturbation have an effect (direct or indirect) on the process?
Ans: yes
