Highly porous and permeable
Explanation:
Compared to other types of rock layers, an aquifer is highly porous and permeable.
Aquifers are always the target when prospecting for ground water in a formation.
- Porosity is the amount of void spaces in a rock.
- Aquifers are highly porous .
- Permeability is the inter-connectivity of the void spaces and their ability to transmit fluids.
- Aquifers have very high permeability compared to other rock types.
In terms of permeability and porosity, an aquifer is higher porous and permeable.
