Pebbles are considered a component of [[sedimentary rock]] and are formed through the process of [[weathering]] and [[erosion]]. The size of pebbles can vary, but they generally range in diameter from 4 to 64 millimeters (0.16 to 2.5 inches), fitting into the [[geology|geological]] category between [[clay]] and [[boulder]].

==Formation==
Pebbles are created when larger rocks are broken down by natural forces. [[Water]], either from rivers or waves, plays a significant role in this process, gradually wearing away the surface of rocks and reducing them in size. The movement of water also rounds and smooths the edges of these fragments, resulting in the characteristic shape of pebbles. [[Ice]] and [[wind]] can also contribute to the formation of pebbles by eroding rock surfaces and transporting small pieces to new locations.

==Composition==
The composition of pebbles is highly variable, depending on the type of parent rock and the specific conditions of their formation and environment. Common materials include [[quartz]], [[granite]], [[basalt]], [[limestone]], and [[flint]]. The color of pebbles can range widely, with hues influenced by the mineral content of the rock from which they originated.

==Locations and Uses==
Pebbles can be found in a variety of settings, including [[beach]]es, riverbeds, and along the shores of [[lake]]s. They are often collected for use in [[landscaping]], [[gardening]], and decorative projects. In addition, pebbles are used in the construction of buildings, paths, and driveways. They also play a role in various cultural and artistic practices, serving as a medium for [[sculpture]] and [[painting]], and in games and ceremonies.

==Environmental Impact==
While pebbles are a natural part of many ecosystems, the extraction of pebbles from their natural environments can have detrimental effects. Removing pebbles from beaches and riverbeds can lead to [[erosion]], loss of [[habitat]] for wildlife, and disruption of natural processes. As such, sustainable practices and regulations are important to minimize the impact of human activities on pebble-rich environments.
