Question

What are the non-stone counter surfaces, arranged softest to hardest?

Answer 1

The non-stone counter surfaces, arranged from softest to hardest, are slatey cleavage, rough surface, and polycrystalline calcite matrix.

Step-by-step explanation:

The non-stone counter surfaces, arranged from softest to hardest, are:

1. Slatey Cleavage: Smooth, flat surfaces with separate grains not visible
2. Rough Surface: Sharp processes, small rounded processes, and elongated ridges with holes and depressions
3. Polycrystalline Calcite Matrix: Dense and brittle material with a corrugated surface
