Inland pebbles (river pebbles of river rock) are usually found along the shores of large rivers and lakes. These pebbles form as the flowing water washes over rock particles on the bottom and along the shores of the [[river]]. The smoothness and color of river pebbles depends on several factors, such as the composition of the [[soil]] of the river banks, the chemical characteristics of the water, and the speed of the [[Water current|current]].  Because river current is gentler than the [[Wind wave|ocean waves]], river pebbles are usually not as smooth as beach pebbles. The most common colors of river rock are black, grey, green, brown and white.
