  1. 1-14-11What is the water cycle? Do Now: What is the difference between sea water and ground water? HW. R&H pp.160-163, A&E #1-25

  2. Water Cycle

  3. 1-18-11Aim- What is the Water Budget? • Do Now- List all factors that would increase run-off. www.youtube.com/watch?v=#919AD3

  4. The Water Budget is a mathematical model of the water cycle for a region.Water Budget Terms (monthly) • (P) Precipitation- the amount of rainfall for the month. • (Ep) Potential Evapotranspiration- temperature or heat that gives potential for this to happen. • (St) Storage- water that is stored in the ground. Ground is full at 100 and empty at 0. • (Ea) Actual Evapotranspiration- actually what has evapotranspirated. Always the same as Ep as long as there is water in the ground. • (D) Deficit- amount of water you are short by. When the St is at 0, and Ep is greater than P, then it is Ep-Ea. • (S) Surplus- when St = 100 and P is greater than Ep

  5. Water budget Usage- when you are using up water in the ground. Recharge- when you are refilling the ground with water

  6. 1-20-11Aim: What factors affect climate • Do Now: • R&H pp. 165-171, What is climate? • HW – A&E #26-61
