Which of the following is NOT considered a surface-water resource? 10.01 Which of the following is NOT considered a surface-water resource? Oceans Rivers Creeks Aquifers Springs ANSWER: D, [p. 302]

10.02 Why is it important to differentiate between confined aquifers and unconfined aquifers? Because an unconfined aquifer contains salt water while confined aquifers only contain fresh water. Because unconfined aquifers are more permeable than confined aquifers and so unconfined aquifers must be protected from pollution if they’re to be used as a resource. Because confined aquifers are more permeable than unconfined aquifers and so confined aquifers must be protected from pollution if they’re to be used as a resource. Because depending on the type of aquifer, scientists can better understand tectonic plate movement in that region. Because unconfined aquifers boast plentiful marine life and so they must be protected.
