Pebbles on Earth exist in two types of locations – on the beaches of various oceans and seas, and inland where ancient seas used to cover the land. Then, when the seas retreated, the rocks became landlocked.{{citation needed|date=May 2024}}  Here, they entered lakes and ponds, and form in [[river]]s, travelling into [[estuary|estuaries]] where the smoothing continues in the sea.

Beach pebbles and river pebbles (also known as river rock) are distinct in their geological formation and appearance.

Manufactured Pebbles-These  are made from natural stones such as marble, granite, and sandstone. Manufactured Pebbles are designed to specified sizes and forms, making them flexible for many purposes.<ref>{{Cite web |date=2024-08-11 |title=How Pebbles Get Manufactured? |url=https://buypebbles.com/how-pebbles-get-manufacturered/ |website=buypebbles.com}}</ref>

=== Beach ===

Beach pebbles form gradually over time as the ocean water washes over loose rock particles. The result is a smooth, rounded appearance.  The typical size range is from 2&nbsp;mm to 50&nbsp;mm. The colors range from translucent white to black, and include shades of yellow, brown, red and green.  Some of the more plentiful pebble beaches are along the coast of the [[Pacific Ocean]], beginning in Canada and extending down to the tip of South America in Argentina. Other pebble beaches are in northern Europe (particularly on the beaches of the [[Norwegian Sea]]), along the coast of the U.K. and Ireland, on the shores of Australia, and around the islands of Indonesia and Japan.

=== Inland ===

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.
