20. Which statement about permeability is most accurate?

A. Sand is more permeable than sandstone.
B. Silt is more permeable than gravel.
C. Sandstone is more permeable than gravel.
D. Clay is more permeable than sand.

The answer is A) Sand is more permeable than sandstone, because sand is a substance made of tangible individual particles, which leave space between themselves and are easily moved around, while sandstone is a substance made of compacted minerals which don’t leave much space between them. The larger spaces between sand allow liquids and gasses to pass through it easier than sandstone, meaning it has more permeability.
