1. Origin:
* River rock: Formed naturally by the erosion and weathering of rocks in rivers. They have smooth, rounded edges due to being tumbled and polished by water currents.
* Crushed gravel: Created by crushing larger rocks into smaller pieces. They have sharp, angular edges.
2. Appearance:
* River rock: Usually comes in a variety of colors and sizes. Their smooth, rounded surfaces create a natural, organic look.
* Crushed gravel: Usually has a more consistent size and color. Their angular shape can create a more industrial or modern look.
3. Applications:
* River rock: Commonly used for landscaping, decorative features, and pathways. Their smooth surface provides a comfortable walking surface.
* Crushed gravel: Used in a wider range of applications, including drainage, construction foundations, and road building. Its angular shape provides better compaction and stability.
In summary:
* River rock is naturally formed, smooth, and used primarily for decorative purposes.
* Crushed gravel is manufactured, angular, and used in both decorative and functional applications.
While they share some similarities as aggregates, their origins, appearances, and applications set them apart.
