A roller is a fragment of rock to look round, smooth.
The rollers are products of erosion
which are transported by rivers or rivers : friction with the other fragments, rocks become smooth, rounded, the rollers take their rounded shape (fluvial pebbles ). They accumulate in the beds of rivers and deltas in . There are also marine pebbles, formed from rock fragments tossed by currents and waves, thus undergoing wear similar to river pebbles. These are pebbles found on beaches, often mixed with river pebbles. abrasion generated by sand and silt carried by water (runoff ,
discharge, sea movements, etc..) On boulders can also generate rollers. can also find the puck in the art, so it serves the material, like Andy Goldsworthy
A resurgence of pebbles has been observed recently on the beaches of Britain and especially around Préfailles
in Loire-Atlantique. This phenomenon is even more surprising that "The rock and its environment," analysis published in March 2008 by Geo shows the evolution of erosive conditions in the northwestern French territories.
