Grain size is the diameter of singular sediment grains, or the lithified particles in clastic rocks. The term may apply to other granular materials, too. This differs from the size of a crystallite, which refers to the size of a single crystal within a particle or grain. Many crystals can be composed of a single grain. Granular material can ...

silt | National Geographic Society
Silt is made up of rock and mineral particles that are larger than clay but smaller than sand. Individual silt particle s are so small that they are difficult to see. To be classified as silt, a particle must be less than .005 centimeters (.002 inches) across. Silt is found in soil, along with other types of sediment such as clay, sand, and gravel.

What type of weathering involves the grinding away of rock ...
Rocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off. What occurs when a rock is scraped by rocks or other particles?

What are the Different Types of Rocks? (with pictures)
There is a lot more involved than what you learn in high school geology, though. Even mere rock identification can get tricky. You can't always tell just by appearance what a rock type is.

For smaller particles, most deposition mechanisms become less efficient, so deposition is less for particles smaller than 2 µm until it is only about 10-15% at about 0.5 µm. Most of these particles are exhaled again without being deposited. For still smaller particles, diffusion becomes an effective mechanism and deposition probability is higher.
