Cobbles on a beach

Sediment is a naiturally occurring material that is broken doun bi processes o watherin an erosion, an is subsequently transportit bi the action o wind, watter, or ice, an/or bi the force o gravity actin on the pairticle itself.

Sediments are maist eften transportit bi watter (fluvial processes), wind (aeolian processes) an glaciers. Beach sands an river channel deposits are examples o fluvial transport an deposeetion, tho sediment an aa eften settles oot o slow-movin or staundin watter in lochs an oceans. Desert sand dunes an loess are examples o aeolian transport an deposeetion. Glacial moraine deposits an till are ice-transportit sediments.
