Carbon and Water Cycles

Carbon and Water Cycles “For dinner last night you ate a dinosaur and drank its wee.” Disgusting but true?

Carbon and Water Cycles 1) If the water cycle is a closed system – where did the water come from originally? Watch this science show and answer the question. 2) Where is most water stored? How does it flow in and out of this store? 3) Where is most carbon stored? How does it flow in and out of this store? 4) Give an example of when the water and carbon cycle operates as an open system. 5) How might human use of fossil fuels be changing the flows and stores of the carbon cycle?

Carbon and Water Cycles Final thought What connections are there between the water and the carbon cycle? See how many you can identify. Additional Challenge Give a more detailed analysis of this question. Use the data in figure 4.2 and consider how you would approach finding out the answer.
