Question

From the choices below, select all the places or rock types that would be good aquifers.

A) Sandstone
B) Granite
C) Clay
D) Limestone
E) Gravel
F) Basalt

Answer 1

Sandstone, limestone, and gravel are good aquifers due to their high permeability and porosity.

Step-by-step explanation:

The rock types that would be good aquifers are Sandstone, Limestone, and Gravel. These rocks have high permeability, meaning they have a lot of interconnected open spaces that allow water to flow through.

Sandstone is particularly good because it has large-scale cross-bedding and well-rounded sand grains, which enhance its ability to hold and transmit water. Limestone and gravel also have good porosity and permeability, making them suitable for groundwater storage and flow.
