difference sizes of gravel and cobbles
Different Types & Sizes of Aggregate for Concrete » Engineering Basic
Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. The size range of various coarse aggregates given below: Fine gravel: 4mm – 8mm. Medium gravel: 8mm – 16mm

Is Cobble bigger than gravel? – Roadlesstraveledstore
A cobble (sometimes a cobblestone) is a clast of rock defined on the Udden–Wentworth scale as having a particle size of 64–256 millimeters (2.5–10.1 in), larger than a pebble and smaller than a boulder. Other scales define a cobble’s size in slightly different terms.

However, beaches may be composed of sediments of various sizes: (from finest to coarsest) mud (silt and clay), sand, and gravel (cobbles and boulders). Scientists generally use Wentworth’s grain-size distribution chart for sediment size analysis. Typically, people associate beaches with quartz sand, however, sand is a grain size (1/16 mm to 2

Gravel Size Gradation Chart which stone to choose
Products in this range are notably more compactible and suited for creating a base layer -such as Crusher Run, Screenings, Sand and Soil. For support of heavy vehicles – choose our #3 or #4 stone. For standard driveways – choose our #57 or #67. For more elaborate driveways – choose our 1/2” to 2” river gravel.

Grain size
Dominant grain sizes are sand, gravel and cobbles. Bimodal bottom type with frequent instances of blocks on the sandy bottom. Bimodal bottom type where cobbles and boulders occure frequently in the areas dominated by fine-gained sediments. Fine-grained sediments with varying content of coarser grain sizes.

What's the difference between stones, rocks, pebbles, boulders, etc
Answer (1 of 4): Stones and rocks and boulders and pebbles are all the same things: rock material. The main difference is size. Stone is generally used for large amounts, rock is just the generic term, boulders are pieces of rock bigger than a foot across or so, and pebbles are smaller than 2.5

Sand and gravel resources | SpringerLink
There is a variety of different size descriptions and classifications that define sands and gravels, such as the Wentworth Grade Scale. This is a geometric grading scale that divides sand into sizes between 0.06 and 2 mm, and gravel into sizes classed as pebbles, from 2 to 64 mm (with cobbles ranging from...

Grain Size : What is Grain Size? How is Grain Size measured?
In typical rivers the largest carried sediment is of sand and gravel size, but larger floods can carry cobbles and even boulders. In a stream, the most easily eroded particles are small sand grains between 0.2 mm and 0.5 mm. Anything smaller or larger requires a higher water velocity to be eroded and entrained in the flow.

Pebble vs. Gravel
Pebble. A pebble is a clast of rock with a particle size of 4–64 mm (0.16–2.52 in) based on the Udden-Wentworth scale of sedimentology. Pebbles are generally considered larger than granules (2–4 mm (0.079–0.157 in) in diameter) and smaller than cobbles (64–256 mm (2.5–10.1 in) in diameter).

What Are the Different Gravel Sizes? (with pictures)
Gravel is often made from crushed rock. There are a number of other mid-range sizes available in many places, too, most of which are designed with specific projects or uses in mind. Size #3, for instance, is usually 1.5 to 2 inches (about 3.8 to 5 cm) in diameter, and is often best for residential draining projects; #8, which is usually 3/8 to 1/2 an inch (1 to 1.2 cm)

1.1 Gravel- and cobble-bed streams: distinctions from other streams
Gravel- and cobble beds usually contain some sand, typically less than 10% in mountainous areas, and maximally up to about 50%. In mountain areas, gravel- and cobble bed streams may also contain large boulders. Thus, the entire range of bed-material particle size can span five orders of magnitude (i.e., from fine sand of 0.06 mm
