Rocks in a stream become smooth through a process called abrasion, where the sediments carried by the water wear down the rocks over time. This continuous rubbing and grinding against each other in the stream smoothens the surface of the rocks.
Essentially, the only types of rock that can stand up to this type of erosion are igneous and metamorphic rocks. I am not certain there is a technical or scientific term for this type of rock, but the colloquial or "slang" term for them is river rocks.
Round rocks can be formed through a process called abrasion, where they are repeatedly tumbled and smoothed by the movement of water, wind, or ice. Over time, the sharp edges and corners of the rocks wear away, resulting in a rounded shape.
Rocks become smooth through the process of weathering, which includes abrasion from wind, water, or ice over time. Rocks that are not smooth may have experienced less weathering or may be composed of harder materials that resist erosion. The smoothness of a rock can also depend on its location, as rocks in a riverbed or along a coastline are more likely to become smooth.
Rocks become smooth and rounded through a process called abrasion. This occurs when the rocks are continuously rubbed against each other or against other surfaces, wearing down their rough edges and surfaces over time. Factors such as water flow, wind, ice, and sand can contribute to this process.

why are most of rocks extremely smooth
Glassy textuered rocks, such as Obsidian.
Rocks in stream beds can become smooth due to a process called abrasion. As water flows over the rocks, it carries sediment and particles that constantly rub against the rocks, wearing them down and making them smooth over time. The friction caused by the movement of water and sediment helps polish the surface of the rocks.
Some feel smooth because it has been eroded away by the current of the water for a very, very long time. The more rough rocks have not been succumb to as much erosion, therefore it is not smooth yet.
Gastroliths were the smooth, rounded rocks that dinosaurs ingested to help them digest and grind their food. These rocks were swallowed and moved around in the stomach to break down tough plant material.
By weathering. The water currents weather the rocks leaving them smooth.

Because it lacks striations the muscle appears to look very smooth under a microscope.
