Which of the following materials has low porosity and low permeability?
A) unfractured granite
B) uncompacted clays
C) limestone with caverns
D) well-sorted sand
Porosity
The measure of void spaces in a material, indicating its ability to hold fluids.
Unfractured Granite
Unbroken or intact granite rock, typically characterized by its hard, coarse-grained structure without significant cracks or breaks.
Permeability
A measure of how easily fluids can pass through a porous rock or sediment.
- Acquire knowledge on the topics of porosity and permeability and their roles in the storage and transport of groundwater.

Final Answer :
A
Explanation :
Unfractured granite has low porosity and low permeability because its solid, crystalline structure leaves very few spaces (pores) between mineral grains, and these spaces are not well-connected, making it difficult for fluids to move through the rock.
