1 By Stephen Monahan

2  1. Draw (or present an image) and describe the steps of the water cycle.  Evaporation: Liquid-> gas (energy of sun)  Transpiration: Gaseous water released from leaves of plants  Condensation: When water particles condense to form rain droplets in clouds  Precipitation: When rain droplets fall to the earth from the clouds

3  2. Define: Evaporation and Transpiration  Evaporation: Liquid-> gas (energy of sun)  Transpiration: Gaseous water released from leaves of plants

4  1. Draw (or present an image) and describe the steps of the carbon cycle.  Photosynthesis: The process of converting sunlight into food  Respiration: The process of converting food into carbon dioxide  Decomposition: The process of flesh decomposing.

5  2. Describe how fossil fuels form.  3. List human activities that increase the amount of atmospheric CO2. Deforestation  4. What type of a gas is CO2? Green House Gas  5. What problem is associated with elevated CO2 levels? Global Warming

6  1. Draw (or present an image) and describe the steps of the nitrogen cycle.  Nitrogen Fixation: Converting Nitrogen Gas into ammonia  Dentrification: Converting nitrates into nitrogen gas

7  2. What percent of the atmosphere is made of Nitrogen (N2) gas? 78%  3. Define and describe Nitrogen Fixation and Denitrification. Nitrogen Fixation: bacteria takes nitrogen gas -> nitrogen compounds Dentrification: Soil bacteria convert nitrates-> Nitrogen gas  4. Why do all organisms require nitrogen? Nitrogen is required to make amino acids

8  1. Draw (or present an image) and describe the steps of the phosphorus cycle.  Weathering: The process of wearing down rocks and sediments which releases phosphate  Some of the phosphate is washed into the ocean  Some Phosphate stays on land and is absorbed by plants  Plants bind phosphate into organic compounds

9  2. Why is phosphorus essential to living organisms? Phosphorus is required to form part of DNA  3. How is the phosphorus cycle different than the other biogeochemical cycles? Phosphorus doesn’t enter the atmosphere  4. Where is most of the phosphorus store In the biosphere? Most phosphorus is stored in land, rock, soil and minerals  5. How does phosphorus become incorporated into organic compounds? Plants bind phosphate for organic use through a food web
