Solution

The best groundwater reservoirs have high permeability and high porosity. So, the answer is a. high permeability and high porosity.

Here's why:

  1. Permeability refers to the ability of a material (in this case, the rock or soil in the groundwater reservoir) to allow fluids to pass through it. High permeability means water can move freely through the material, which is important for a groundwater reservoir as it allows the water to be extracted more easily.

  2. Porosity refers to the amount of empty space within a rock or soil. High porosity means there are many spaces or "pores" in the material that can store water. This is also important for a groundwater reservoir as it increases the amount of water that the reservoir can hold.

Therefore, for a groundwater reservoir to be effective, it needs to have both high permeability (to allow water to be extracted) and high porosity (to store large amounts of water).

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.
