Question
Marc Reisner predicted a groundwater overdraft in the San Joaquin Valley of up to 1 trillion gallons per year by the year 2000. How many zeros does one trillion have and how many acre- feet of water is 1 trillion gallons? How does this amount of water compare with the storage capacity of a good sized reservoir like Lake Isabella? Marc Reisner predicted a groundwater overdraft in the San Joaquin Valley of up to 1 trillion gallons per year by the year 2000. How many zeros does one trillion have and how many acre- feet of water is 1 trillion gallons? How does this amount of water compare with the storage capacity of a good sized reservoir like Lake Isabella?Explanation / Answer
--->1 trillion has 12 zeros 1 gallon = 3.06 x 10-6 1 trillion gallon = 3.06 x 10-6 x 1012 ---> 1 trillion gallon has 3.06 x 106 acre feet Capacity of Lake isabella = 568,000 acre feet Calculated capacity is 3060000. ---> calculated capacity is 3060000 / 568000 = 5.38 times bigger than the capacity of lake Isabella
