River beds.
At the bottom of an ocean, deep within earth, on the top of a hill, and in a fast-moving river.
in the ocean or river :P

river beds
A lot of rocks have sat in water at one time or another, and flowing water erodes minerals, giving rocks a smooth, rounded shape over time.
tumbling against other rocks and sand, either in a stream or in a rock tumbler.
Sediment carried by the river acts as an abrasive against the rocks on the bottom of the river. Rocks are also continually bounced into each other, which also serves to gradually knock off rough edges, making them smoother and rounder.
Rocks that are composed of rounded grains or fragments are usually sedimentary rocks. Two of these are sandstone and conglomerate rocks.
Because the tides act as a rock tumbler, it slowly smooths them out.More Information:Rocks found on beaches can be smooth for various reasons. The most common is that the washing motion of the waves erodes the sharp corners off over time by knocking little bits of sand and clay into them.Rocks along beaches can also be smooth if they happened to be deposited by glaciers. Rocks brought to a location because of the moving of glaciers long ago are rounded by tumbling around in front of the glaciers.

Erosion and weathering will cause rocks to become rounded.
rocks are called gastroliths
They fragment and become jagged, they become rounded by means of water erosion, which is why rounded rocks are found by rivers, creeks, etc.
Erosion causes them to become smooth from wear.

form the sand & water moving it
They become smooth and oval shaped, because the rushing water erodes the rock fragment/s.
Rocks usually start off as angular objects with edges and corners. After abrasion the edges and corners get removed and the rocks end up smooth and more rounded, they also get smaller.
why are most of rocks extremely smooth
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.
it will become rough because it scraped against the other rocks wearing it away
