Which of the following materials probably has the lowest porosity?

A) well sorted, fine-grained sediment
B) well sorted, coarse-grained sediment
C) unfractured granite
D) sand with well-rounded grains

Porosity

The measure of void spaces in a material, indicating the volume percentage of pores or spaces between particles.

Unfractured Granite

A type of igneous rock, characterized by its large crystals and lack of cracks or fractures, often used in construction due to its strength.

Fine-Grained Sediment
