1. SCIENCE 8 TOPIC 10

2. Naming and describing the water budget terms

3. #1: P stands for precipitation

4. #2: Ep stands for potential evapotranspiration

5. #3: P-Ep stands for precipitation minus potential evapotranspiration

6. #4: storage stands for change in storage

7. #5: ST stands for storage

8. #6: Ea stands for actual evapotranspiration

9. #7: D stands for deficit
You’ll like Mr. Clement…he has attention deficit disorder

10. #8: S stands for surplus

11. The difference between Ep and Ea

12. The difference between Ep and Ea
Potential evapotranspiration is how much water wants to be taken away IF THE CONDITIONS PERMIT
Actual evapotranspiration is how much water is really taken away

13. The relationship between Ep and insolation
Direct, because as insolation increases Ep increases because more of the sun’s energy is available to evaporate and transpire away water

14. Now we’ll start Topic 10b

15. The definition to a stream

16. The definition to a stream
A channel in the earth where run-off water collects and then moves downhill

17. The two sources of water for a stream

18. The two sources of water for a stream
Surface run-off

19. The two sources of water for a stream
Ground water

20. The base flow of a stream

21. The base flow of a stream
Ground water only

22. How climate regions are classified

23. How climate regions are classified
By the temperature averaged over the year

24. How climate regions are classified
By the temperature averaged over the year
By the moisture pattern: P - Ep

25. What are four major climate regions?

26. What are four major climate regions?
humid

27. What are four major climate regions?
humid
arid

28. What are four major climate regions?
humid
arid
subhumid

29. What are four major climate regions?

30. Some factors that modify latitudinal climate patterns

31. Some factors that modify latitudinal climate patterns
1. The latitude – closer to zero degrees will generally have colder/dryer climates

32. Some factors that modify latitudinal climate patterns
2. The elevation – generally cooler temperatures are found at higher elevations

33. Some factors that modify latitudinal climate patterns
3. Areas near large bodies of water – generally have cooler summers and warmer winters as well as higher humidity

34. Some factors that modify latitudinal climate patterns
4. Planetary wind belts – these bring climate changes depending on where they come from

35. Some factors that modify latitudinal climate patterns
5. Ocean currents – these bring climate changes depending on where they come from

36. Some factors that modify latitudinal climate patterns
6. Mountain ranges – windward side is cool/moist and leeward side is warm/dry

DIVIDE THE TOTAL AMOUNT OF STREAM FLOW IN EACH MONTH BY THE NUMBER OF DAYS IN THAT MONTH. ROUND OFF YOUR ANSWER TO THE NEAREST THOUSANDTH’S PLACE AND WRITE THAT NUMBER IN THE BOX UNDER THE NAME OF THE MONTH
