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.
They may be smooth and others may be rough. Smoothness/roughness is not a defining characteristic for igneous rocks.
rocks are called gastroliths
The tides and waves slowly wear away at the rocks.
because of water
why are most of rocks extremely smooth
By weathering. The water currents weather the rocks leaving them smooth.
Plants are the organisms which have roots and can crack rocks
mica
some from weathering
cause rocks r dumb

skipping stones!
River rocks, because have smooth edges.

clay, smooth rocks and mud
Erosion causes them to become smooth from wear.
