The capacity of rocks and soil to allow water to pass through them easily is called what?

Answer and explanation

Correct answer: Permeability

The correct answer is B, permeability. Permeability is the ability of a material to allow a fluid, such as water, to move through connected pores, cracks, or openings. In soil and rock, water can pass readily when the spaces are connected and provide a continuous pathway. A, porosity, means the amount or percentage of empty space in a material. A rock may have many pores but still be poorly permeable if those pores are not connected. C, absorption, means taking in or holding a substance, not necessarily allowing it to flow through. D, density, is mass per unit volume and does not directly describe water movement. Memory cue: porosity asks “how much empty space?”; permeability asks “can water travel through connected space?”
