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.
