Question

Based on the macroscopic views of the three substances, which is most permeable? gravel sand silt impossible to tell

Answer 1

Gravel

Step-by-step explanation:

Gravel is a material that has high permeability. Gravel is widely used as a material for paving, because it is a material of lower cost offering savings for construction, for this reason, it is easily found in parking lots, bicycle paths, sidewalks, among others. Its permeability allows that when a liquid reaches it, it can drain through the gravel pores very easily.

Answer 2

The answer is Gravel. Permeability is the ability a substance or material to allow gases or liquids to go through them. Gravel has the ability to allow passage of fluids such as water and gases to pass through it in comparison with sand and clay whose permeability is low based on microscopic views.
