Question 2

"The drinking water in our town is always cold, clear, and pure because it comes from an artesian well." Briefly discuss the geologic validity of this statement.Although this idea wasn't specifically discussed in Chapter 16, give a possible reason or two as to why such statements are often made.

Accepted Answer

In artesian aquifers, water commonly flows a long way allowing it to be purified.It is often cold because the aquifer tends to parallel a surface slope and therefore is not affected much by the geothermal gradient.

Question 3

How are travertine or silica deposits formed from boiling geysers and related hydrothermal systems?

Accepted Answer

A) Boiling off steam forces the remaining hot solution to be saturated or supersaturated as the same mineral content is now concentrated in less water and it precipitates. 
B) More gases enter the system once boiling starts forcing precipitation. 
C) As pressures increase less mineral matter is soluble. 
D) By introduction of cold fresh recharge water which quenches the system.
