APES Chapter 9Dams and Salmon on the Klamath River - correct answer hydroelectric dams, in conjunction with the drainage of two large lakes at the river's source for agriculture, impeded the flow of water and prevented the natural migration of salmon to their breeding grounds; conflict over water use between farmers, fisherman, Native Americans, industry, etc. led to overuse and exploitation of this resource and massive fish kills (increased temperatures, disease, toxic algae); the dams are sch...

Chapter 9 Questions Explain the difference between a confined and an unconfined aquifer - correct answer An unconfined aquifer is an aquifer where water can easily flow in and out. A confined aquifer has an impermeable, or confining, layer which impedes water flow to or from the aquifer What is saltwater intrusion and what causes this problem? - correct answer Saltwater intrusion occurs when saltwater mixes with freshwater and contaminates well water. It is common in coastal areas. This happ...

GEO CHAPTER 17 STUDY GUIDE EXAM QUESTIONS 2024. Which of the following characteristics are found in all good aquifers? - correct answer High porosity and high permeability Which of the following accounts for the largest usage of groundwater in the United States? - correct answer Agriculture and irrigation An artesian well is one in which... - correct answer Water rises above the top of the aquifer without any pumping A ________ is the icicle-like speleothem that grows down from the roo...

Water ResourcesWatershed - correct answer An area or ridge of land that separates waters flowing to different rivers, basins, or seas. Unconfined aquifer - correct answer An unconfined aquifer, also called a water-table aquifer, is an aquifer which has the water table as its upper boundary. Unconfined aquifers occur near the ground surface. Confined aquifer - correct answer A confined aquifer is an aquifer that is bounded above and below by confining beds. Confined aquifers generally occur...

Freshwater is a limited resource and we are using it faster than it can be replenished. Although methods are available to recover and purify some of the water we use, conservation is also seriously needed. T or F - correct answer True Case: The Orange County Water District (OCWD) in Anaheim, CA has begun a groundbreaking project to turn wastewater into drinking water. T or F - correct answer Tru On a planet covered with water, why is its availability becoming a crisis? - correct answer A...

Aquifer Questions and Answers latest updated The porosity and permeability of an aquifer define its ability to yield water to wells in productive amounts. true For some wells along the coastline that are drilled into porous aquifers, pumps are turned off twice a day (during periods of high tides), since tides temporarily raise saline groundwater levels, causing saltwater intrusion into freshwater aquifers. false Most wells are shallow because a significant amount of water cannot...

Barrier beaches CORRECT ANSWER Narrow and elongated beaches situated parallel to the shoreline Development of barrier beaches CORRECT ANSWER Usually formed as an extension of a spit, longshore drift moves sediment along coastline and when coast suddenly changes direction (e.g. across a river mouth) longshore drift continues to deposit material, resulting in the formation of a spit. When the spit joins two headlands, it becomes a bar/barrier beach. What forms behind a barrier beach? CORRECT...
