Which of the following materials is the least porous? A. loosely packed gravel B. sorted sand and rock C. unsorted sand and rock D. large pebbles and boulders

Respuesta :

Sorted sand and rock is the least porous material.

 

Sorting describes the distribution of grain size of sediments, either in unconsolidated deposits or in sedimentary rocks. Very poorly sorted indicates that the sediment sizes are mixed (large variance); whereas well sorted indicates that the sediment sizes are similar (low variance).

 

The correct answer between all the choices given is the second choice or letter B. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

A porous medium or a porous material is a material containing pores (voids). The skeletal portion of the material is often called the "matrix" or "frame". The pores are typically filled with a fluid (liquid or gas).
B.Sorted sand and rock  are the least porous materials.
