Worn, round fragments of rock, occurring in natural deposits, small enough to pass through a two and one-half inch iron ring and large enough to be retained on a No. 10 screen.
Rounded or angular fragments of rock up to 3 inches (2 millimeters to 76 centimeters) in diameter An individual piece is a pebble.
Rounded to angular particles of rock that will pass a 3" sieve (75mm) and are retained on a #4 sieve (4.17mm).
The coarsest clastic sediment, consisting mostly of particles larger than 2 mm and including cobbles and boulders.
Is a non-coherent natural mineral aggregate from natural disintegration of rock. It consists mainly of rounded pebbles for sub-angular rock fragments. It normally occurs in sand and gravel deposits or detritus.
Soil particles ranging from 1/5 inch to 3 inches in diameter
loose rounded fragments of rock Minnesota: Modern Farming
(non processed) The principle paving material, and in all probability the oldest paving material. It is of course important to select a high quality paving gravel. River washed round gravel is soft and not as compact able as most processed gravel's (see processed gravel). Sharp stone gravel in a range of stone sizes self binds to form a smooth and stable surface. Natural or riverbank gravel's can have a wide variety of stone sizes but also have less compact ability.
rock fragments and pebbles

A natural material applied to tar and gravel roofs. This coarse, granular aggregate contains small pieces approximately 5/8 inch to 1/2 inch in size.
Composed chiefly of quartz but may contain granite, limestone, basalt and other rocks.
Small stones or fragments of stone or very small pebbles larger than the particles of sand, but often mixed with them. Generally 4.76 to 75mm in size. (Stones 75 to 300 mm are usually called "cobbles".
A rock fragment with a diameter ranging from 2 to 64 mm.
A sediment grain with a diameter of 2-20mm
Sediment particles that are between 4-16 mm in diameter
A loose mixture of pebbles and rock fragments that are coarser than sand.
rock measuring 0.5 to 2.5 inches in diameter with no more than three percent of the material passing a number 200 sieve screen (0.074 millimeter diameter openings).
grains with diameters between 2 and 4 mm
The by product of eroded riverbed rocks, gravel is a culmination of very fine grained particles of rock, sometimes referred to as a type of soil.
Loose fragments of rock used for surfacing built-up roofs, in sizes varying from 1/8" to 13/4."
Accumulation of small, smooth, rounded rock deposited by a stream or river.
Coarse, granular aggregate, containing pieces approximately 5/8 inch to 1/2 inch in size and suitable for use in aggregate surfacing on built-up roofs.
All sedimentary particles larger than two millimeters is called gravel. Gravel is subdivided into pebbles, cobbles, and boulders. more details...
Rounded rock fragments larger than sand.
Naturally rounded or mechanically crushed stones ranging in size from 3/8 to 1 1/2 inches. Often used for driveways, pathways and water features. Example: Black Chip
A natural accumulation of rounded rock pieces that are the products of erosion of an original parent material.
A cohesion less aggregate of rock fragments with varying dimensions of 3.0 to .08 inches.
A mixture of small stones and pebbles, sometimes combined with sand.
Soil particles (%w) larger than course sand (2000 Î¼m; 2mm) which do not hold soil water by matrix tension and do not conduct water movement.

Aggregate resulting from the natural erosion of rock.
A collection of loose, rounded fragments of rock, such as pebbles.

Gravel is rock that is of a certain grain size range. In geology, gravel is any loose rock that is at least two millimeters in its largest dimension (about 1/12 of an inch) and no more than 75 millimeters (about 3 inches). Sometimes gravel is restricted to rock in the 2-4 millimeter range, with pebble being reserved for rock 4-75 millimeters (some say 64 millimeters).
