How are rock fragments classified?
Rock fragments are typically classified based on the size of the individual pieces that make up the aggregate. For example, sand is made up of rock fragments smaller than those in gravel, while gravel is smaller than cobbles, and cobbles are smaller than boulders. Size classifications of rock fragments (and gravel) can vary. Two commonly used standards are the Udden-Wentworth scale (a scale commonly used by geologists in the US) and the international standard, ISO 14688. In the Udden-Wentworth scale, gravel is categorized as granular gravel if it is 2-44 mm (0.079-0.157 in) in diameter or pebble gravel if it is 4-66 mm (0.2-2.5 in) in diameter. On the other hand, ISO 14688-1:2002 classifies gravel as fine (2.0-6.3 mm), medium (6.3-20 mm), or coarse gravel (20-63 mm).

Unlike many organic mulch types, gravel is also less prone to moving, so it is more likely to retain a desired shape or form when subjected to the elements.
Is gravel smoother than crushed stone?
Gravel formed as a result of natural erosion tends to be smoother and rounder while crushed stone will have rougher edges and be less smooth.
