CYCLES IN THE BIOSPHERE
Directions: You will be using the Internet to explore important cycles. Use the suggested websites given below and find others to help you gather
information about the Nitrogen, Carbon, and Water cycles.
WATER CYCLE
Websites:
 http://www.sweetwater.org/education/watercycle.swf
 http://earthguide.ucsd.edu/earthguide/diagrams/watercycle/index.html
Draw the WATER cycle here (be sure to label all processes – evaporation, transpiration, condensation, precipitation, run-off, percolation)
What is the importance of the water cycle to the ecosystem? To humans?
How do humans affect the cycle?
