CARBON CYCLE

Question 1

what is the carbon cycle

Answer 1

a model showing how carbon moves between reservoirs

both natural and man-made processes that effect cycle

Question 2

carbon reservoirs

Answer 2

• rocks
• organisms
• water
• atmosphere

Question 3

carbon reservoirs inputs - rocks

Answer 3

carbonate minerals form when carbon atoms bond with dissolved ions in water from chemical weathering of previous rock and precipitate out

fossil fuels containing carbon form in rock when organisms are buried and transform over millions of years

Question 4

carbon reservoirs output - rocks

Answer 4

volcanic eruptions release co2 that was dissolved in magma into atmosphere

Question 5

carbon reservoirs inputs - organisms

Answer 5

plant photosynthesis

Question 6

carbon reservoirs output - organisms

Answer 6

breathing/dead organism decompose

Question 7

carbon reservoirs inputs - water

Answer 7

bodies of water dissolve carbon from the atmosphere

Question 8

carbon reservoirs output - water

Answer 8

bodies of water release dissolved carbon to atmosphere

carbon and dissolved ions bond to precipitation carbon minerals, forming rock

Question 9

carbon reservoirs inputs - atmosphere

Answer 9

volcanic eruptions release co2 that was dissolved in magma into atmosphere

breathing/dead organism decompose

bodies of water dissolve carbon from the atmosphere

Question 10

carbon reservoirs output - atmosphere

Answer 10

plant photosynthesis

bodies of water dissolve carbon from the atmosphere

Question 11

areas people affect which are part of the carbon cycle

Answer 11

• rocks
• organisms
• water
• atmosphere

Question 12

areas people affect which are part of the carbon cycle - rocks

Answer 12

removing fossil fuels from rocks decrease carbon in rock reservoirs

Question 13

areas people affect which are part of the carbon cycle - organisms

Answer 13

burning plants, mainly trees increase input of carbon into atmosphere

Question 14

areas people affect which are part of the carbon cycle - water

Answer 14

increase carbon in atmosphere means increased carbon dissolved into bodies of water

co2 chemically reacts with water to from carbonic acid, making water bodies more acidic

Question 15

areas people affect which are part of the carbon cycle - atmosphere

Answer 15

burning fossil fuels releases carbon into atmosphere. additional carbon increases intensity of greenhouse effect
