Problem 3
If you collect a jar of water from a stream, what part of its load will settle to the bottom of the jar? What portion will remain in the water indefinitely? What part of the stream's load would probably not be represented in your sample?
Problem 6
Which one of the three basic rock types (igneous, sedimentary, or metamorphic) is most likely to be a good aquifer? Why?
Problem 7
What is the likely difference between an intermittent stream (one that flows off and on) and a stream that flows all the time, even during extended dry periods?
Problem 8
The cemetery in this photo is located in New Orleans, Louisiana. As in other cemeteries in the area, all of the burial plots are above ground. Based on what you have learned in this chapter, suggest a reason for this rather unusual practice.
Problem 11
This black-and-white photo from the 1930 s shows Franklin Roosevelt enjoying the hot springs at the presidential retreat at Warm Springs, Georgia. The temperature of these hot springs is always near \(32^{\circ} \mathrm{C}\) \(\left(90^{\circ} \mathrm{F}\right)\). This area has no history of recent volcanic activity. What is the likely reason these springs are so warm?
