Problem: Process: - An isotope has too many protons - The isotope is unstable - The isotope emits radiation - The isotope decays - The isotope loses some atomic particles - The isotope turns into a different element - The isotope is finished decaying and emitting radiation. Question: suppose less radioactive decay happens happens, how will it affect LESS radioactive decay occurring. - A: more - B: less - C: no effect

A: A

Problem: Process: - Aluminium cans are put into a recycling bin - Aluminium cans are then collected and taken to a treatment plant - At the treatment plant the aluminium is sorted and cleaned - Readied for reprocessing - The aluminum cans go through a re-melt process - Turned into molten aluminium - The molten aluminum is made into large blocks called ingots - The ingots are sent to mills and are rolled out into thin sheets - The rolls are ready to be made into new aluminum products. Question: suppose less exercise occurs happens, how will it affect MORE aluminum cans being recycled. - A: more - B: less - C: no effect

A: C

Problem: Process: - A dam is built in an area prone to flooding - A large amount of rain occurs - The water builds up behind the dam - The dam opens its floodgates when it starts to get full - The water flows into a river below the dam - The dam closes its gates - The dam will occasionally open its gates again to gradually release more water - Eventually all of the floodwater will be slowly released into the river without causing any flood damage. Question: suppose the floodgates will open and close properly happens, how will it affect DEGRADED safety from flooding. - A: more - B: less - C: no effect

A: B

Problem: Process: - Coal is harvested from a coal mine - The coal is transported either by train or truck to power station - The coal is burned in a furnace - Water is turned into steam in the boiler - The steam is cooled in cooling towers - The steam turns the turbines - The generator makes electricity - The electricity is sent through transformers. Question: suppose smaller fault lines happens, how will it affect fewer people want to buy coal. - A: more - B: less - C: no effect

A:
C
