Question

As a hydrogeologist looking for a source of water for a housing development, which of the following attributes would you look for in a layer of sediment or sedimentary rock?

a. Low permeability
b. Low porosity
c. Extent over a large geographic area
d. High porosity and high permeability

Answer 1

A hydrogeologist would look for sediment or sedimentary rock with high porosity and high permeability in their search for a source of water for a housing development.

Step-by-step explanation:

As a hydrogeologist looking for a source of water for a housing development, you would look for sediment or sedimentary rock with high porosity and high permeability. Porosity refers to the open or void space within the rock, and sedimentary rocks tend to have high porosity due to the abundant spaces between the grains. Permeability refers to the ability of a geologic material to transport fluids, and rocks like sandstone and limestone are good aquifers because they are permeable.
