The Water Cycle	The Carbon Cycle	The Nitrogen Cycle	Human Impact	Miscellaneous
100 liquid water that is not infiltrated and collects on the surface into bodies of water What is runoff?	100 Combustion Which phase of the carbon cycle releases carbon dioxide through burning?	100 Bacteria What is nitrogen fixation primarily carried out by?	100 Deforestation decreases transpiration; building development increases runoff and decreases infiltration; pollution; eutrophication What is an example of negative human impact within the water cycle?	100 the water cycle Which biogeochemical cycle is driven by the sun?
200 when the sun heats liquid water into vapor that is released into the atmosphere What is evaporation?	200 True True or false - everything has carbon in it.	200 Decomposition When bacteria break down dead matter and return nitrogen back into the soil this is known as what?	200 combustion - when fossil fuels are burned it releases tons of carbon into the atmosphere What is an example of negative human impact within the carbon cycle?	200 Every step requires a living organism How is the nitrogen cycle different from all other cycles?
300 runoff, evaporation, infiltration, transpiration, condensation, and precipitation What are the six steps of the water cycle?	300 Elimination What always follows consumption?	300 Ammonification When bacteria convert waste (urine and feces) into ammonia this is known as what?	300 fertilization causes an imbalance of way too much nitrogen in the soil; combustion also releases nitrogen into the atmosphere What is an example of negative human impact within the nitrogen cycle?	300 False - only carbon and nitrogen change chemical forms True or false - water can change chemical forms.
400 transpiration - trees release water back into the atmosphere through stomata What is the step of the water cycle that requires living organisms in order for it to happen? Why?	400 They remove CO2 from the atmosphere and convert it into simple sugars (photosynthesis) How do plants and algae contribute to the carbon cycle?	400 Nitrification Which stage of the nitrogen cycle is responsible for nitrogen entering the food chain and ultimately getting to us?	400 when a body of water becomes overly enriched with nutrients, causing excessive algae growth What is eutrophication?	400 Hydrologic cycle What is another name for the water cycle?
500 (answers will vary) Have a member of your team draw the water cycle including all 6 steps on the white board.	500 Cellular respiration and combustion How is the majority of carbon released into the environment (2 answers)?	500 Bacteria What is the most important living organism in converting nitrogen to other forms?	500 Travel, food choices (eating a lot of meat), fast fashion, etc. What are some other ways humans can impact the carbon cycle? Give me fresh ideas!	500 Since matter can neither be created nor destroyed, and Earth is a closed system Why must these essential nutrients always be cycled?
