Which statement is not true for confined aquifer? Options :Sandwiched between two impermeable layers of rock or sediments.Recharged only in those areas where the aquifer intersects the land surface or faults.Significant portion of the rock is directly open at the surface of the groundwater is directly recharged.Sometimes the recharged area is hundreds of kilometers away from the location of the well.

Tick the appropriate option(a) The groundwater table present above the water table of Influent river(b) The effluent river recharges the groundwater(c) The influent river originated from wastewater treatment plant(d) The effluent river is a good example of unconfined aquifer.Only (a) is correctOnly (b) is correctOnly (d) is correctNone of this

Discuss the role of rocks in groundwater storage and the formation of aquifers.

Shale is a relatively impermeable type of rock, while sandstone is permeable to water. In some areas, the ground is made of mostly sandstone with a layer of shale deep underground. Groundwater can seep into the layers of sandstone and be stored above the layers of shale. At a fault line, rock layers are often shifted, sometimes causing layers of shale to reach the surface.Based on this information, what conclusion can be made about groundwater? A. Plate movement creates groundwater reservoirs by breaking impermeable rock layers into permeable rock. B. Groundwater is most abundant near faults and least abundant in the middle of tectonic plates. C. Tectonic activity can cause the amount of groundwater to differ by changing the position of impermeable rock layers. D. Geologic processes increase the amount of groundwater over time by causing shale layers to sink deeper underground.

Why is water from an aquifer more likely to be cleaner than water from other sources? A. because it forms where fresh and salt water meet B. because it receives water directly from precipitation C. because it rises to the surface near the ocean D. because pollutants are filtered by rock and soil deep within Earth
