GEOL 03 Chapter 12 QuizMost of the water falling as precipitation flows to the streams as surface run-off. - correct answer True What will happen to the water table if withdrawal exceeds recharge? - correct answer The water table decreases The country of Libya is located above the Nubians Sandstone aquifer, where gives it access to an account of water about equal to all of the Great Lakes. Despite this, much of the water cannot be used. Why not? - correct answer Two large cones of depression, resulting from source wells, make the water inaccessible. Groundwater contamination is always caused by the infiltration of toxic chemical to an aquifer. - correct answer False On average, how rapidly does water move in an aquifer? - correct answer Centimeters to meters per day Where would you be most likely to find an artesian aquifer? - correct answer Where there are dipping rock units with an overlying aquitard. An aquifer is the same as an underground river. - correct answer False Why are the recently drilled water wells in Bangladesh contaminated? - correct answer Natural chemicals Which rock property is associated with connected spaces? - correct answer Permeability Which condition most accurately describes what is happening in the High Plains Aquifer? - correct answer Aquifer is being depleted Permeability is a measure of porosity. - correct answer False Federal laws protect wetlands from being destroyed during development. Builders are required to replace any but Lansdale propose to fill in with another equivalent (or better) wetlands elsewhere. Suppose a developer fills in a wetland upstream from where you live and relocate it out of the local drainage basin. What would happen to runoff in the stream near your house? - correct answer Runoff would increase What rock property is present in an aquitard? - correct answer Low permeability Which material typically has the lowest permeability? - correct answer Clay Wetlands must be covered with water all year. - correct answer False The elevation of the water table generally follows the topography of the land. - correct answer True One day you are working through some 150 year old maps in a local historical society near an urban area as part of a study. What would you like notice about the amount of wetlands on those maps compared to today? - correct answer Wetlands have decreased in area A groundswell is pumped for a period of time creating a cone of depression. How will the water table appear several days after pumping stops? - correct answer Diagram B When does a cone of depression form? - correct answer When withdrawal exceeds recharge Suppose a water monitoring well near in old landfill has been found to be contaminated with a cancer-causing chemical. The world is about 5000 meters (about 3 miles) away from a housing development that depends on well water. Assume a slow groundwater flow rate of q0 centimeters (0.1 meter) per day. When might the chemical contaminate wells in the development? - correct answer 50,000 days What type of soils are present in wetlands? - correct answer Hydric
