The percentage of pore space between the particles inside a rock or soil is called:
Show answer & explanation
Correct answer: A
Explanation
The Correct Answer is option 1 i.e. Porosity.
Porosity refers to the percentage of pore space (empty spaces) between particles within a rock or soil. These pores can be filled with air or water and determine how much fluid the material can hold or transmit. Porosity is an important concept in geology, agriculture, and hydrology, as it affects water retention in soil and groundwater movement in rocks. High porosity means more space for water or air, while low porosity indicates tightly packed particles. It is distinct from permeability, which describes how easily fluids can pass through those pores.
Other options :
-
Salinity: Refers to the concentration of salts in water or soil.
-
Permeability: Measures how easily fluids can flow through a material.
-
Density: Refers to mass per unit volume, unrelated to pore space.
