Pebble Is a Rock Fragment Which is Smaller Than a Cobble. They are Rounded And/or Elliptical in Shape, Having Diameter Between 10 & 150 mm. Due to Erosion Effect These Rock Fragments Gets Naturally Tumbled With Flowing River Water From Mountains Towards Planes, Making its Surface Smooth.

Cobbles Are Larger Fragments of Different Rocks Ranging From 64 to 256mm in Diameter.

Pebbles Are Mid-Size Particles of Rocks Ranging Between 4 to 64mm Diameters.

Gravels or Granules Are of The Smallest Particle Size of 2 to 4mm Diameters.

Types of Pebbles:

Based on the locations the pebbles found, we can classify them into the beach pebbles and river pebbles. The formation of the beach pebbles takes place due to the washing activities of sea currents. Similarly, river pebbles are forming by the flow of river water.

Properties of Pebbles:

Since pebbles are clasts of rocks; they carry almost all physical and chemical properties of parent rocks. Therefore, pebbles are similar to natural stones in colors, textures, grains, veins, strength, durability, and water absorption rates.

Uses of Pebbles:

In other words, pebbles are miniatures of natural rocks, which are eventually turning into different sizes, smoothness, colors, and textures. Thus, pebbles have distinct usages compared to natural stones available for commercial and construction purposes. The most auspicious use is in the decoration purposes for interior and exterior spaces.
