What size is categorized as a pebble in sediment classification?

In sediment classification, pebbles are categorized as particles that range from 10 mm to 75 mm in diameter. This classification is part of a broader system used to categorize sediment by size, which helps in understanding sediment transport and sedimentary processes. Recognizing the size of sediment grains is important for various applications, including geological surveys, erosion and sediment control practices, and habitat assessments in aquatic environments.

The specified range of 10 to 75 mm is significant because it clearly delineates pebbles from other sediment classifications, such as sand or cobble. Thus, understanding and accurately identifying these size categories aids in effective management of erosion and sediment processes in various environmental contexts.
