In the field, geologists normally classify silt + clay together as mud (pelitic grain size), comprising all grain sizes < 0.0625 mm. Why is grain size important? Siliciclastic sedimentary rocks are the result of erosion, transport, and deposition.

Boulder is the largest particle size, followed by cobble, pebble, gravel (or granule), sand, silt and clay. It takes energy to move particles. The larger or heavier the particle, the more energy it will take to move it.

Gravel is an overall name for large sediment grain size, which includes boulder, cobble, and pebble. Sand includes sediment grains ranging in size from 2mm to 0.625 mm. Silt is the name of a sediment grain that range in size from 0.625 mm to 0.0039 mm. Mud is the smallest grain size and is also known as clay.

Granular material can range from very small colloidal particles, through clay, silt, sand, and gravel, to boulders. Size ranges define limits of classes that are given names in the Wentworth scale (or Udden-Wentworth) used in the United States.

Boulder is the largest particle size, followed by cobble, pebble, gravel (or granule), sand, silt and clay. It takes energy to move particles. The larger or heavier the particle, the more energy it will take to move it. Lower the energy level and the particle will be deposited instead of moved. The image below illustrates this point.

Clastic sedimentary rocks may have particles ranging in size from microscopic clay to huge boulders. Their names are based on their clast or grain size. The smallest grains are called clay, then silt, then sand. Grains larger than 2 millimeters are called pebbles. What do pebbles look like?

Size refers to the diameter of fragments or grains making up a rock. Names used for size, ir order from coarsest to finest are: -Boulder-Cobble-Pebble-Sand-Silt-Clay "Gravel"= accumulation of pebbles + cobbles "Mud"= wet clay Clay: extremely small clasts- typically consist of clay minerals, but specs of quartz may be included.

Particularly in Britain, the term shingle is used to describe the size range covered by beach pebbles, but the word lacks precision and cobbles are sometimes also included. Because of continuing ambiguity, terms such as boulder, cobble, pebble, sand, silt, clay, and gravel need to be defined at the outset of any individual paper or report.

For example, sand (1–2 mm) spans the catchment's full range of cooling ages and therefore source elevations; coarse gravel (16–32 mm) has few young ages, suggesting that most of it comes instead from higher elevations; and boulders (>256 mm) have few old ages, suggesting that these largest clasts preferentially originate at lower elevations ...
