Question 37 (1 point) You have drilled two monitoring wells, A and B, to the water table. At Well A, the water table is 600 feet. The water table at Well B is 400 feet. Both elevations are relative to mean sea level. Well A is located due north of Well B. The distance between Well A and Well B is 1000 feet. What is the hydraulic gradient of this aquifer based on the elevations of water table given above and the distance between Wells A and B? 0.1 0.20 0.25 1.0 5.0 10 Question 35 (1 point) True/False. Potable water is to designate the natural waters that are drinkable. True. False. Question 36 (1 point) With respect to the Rock Cycle, -_-_-_ is/are formed first from the combined effects of physical and chemical weathering on uplifted (exposed, mountainous) bedrock (sedimentary, igneous and/or metamorphic). Clastic sediments. Clastic sedimentary rock. Igneous Rock. Metamorphic rock. Metasedimentary Rock. Question 40 (1 point) Two water wells are located 2000 feet apart at the surface. These wells were drilled to gather groundwater samples and determine the water table elevation. Given the groundwater velocity 20 feet/day and distance of 2000 feet, how long does it take for water to move by subsurface flow from one well to the other well? 20 days. 100 days. 200 days. 1000 days. 2000 days
