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. This type of beach has armoring characteristics with respect to wave erosion, as well as ecological niches that provide habitat for animals and plants. Beach pebbles and river pebbles (also known as river rock) are distinct in their geological formation and appearance. Basalt is an extrusive rock, meaning it formed when lava cooled above the surface of the earth's crust.

River rocks have many common applications, including as landscaping, decorative ground covers and construction material for wall facades and walkways and for use in interior design projects. Pebbles left above the high water mark may have growths of organisms such as lichen on them, signifying the lack of contact with seawater. 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 current. Here, they entered lakes and ponds, and form in rivers, travelling into estuaries where the smoothing continues in the sea. This composite nature results in a huge variance in coloration, with hues ranging from gray and black to white, green, purple and russet.Pebble tools are among the earliest known man-made artifacts, dating from the Palaeolithic period of human history. 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. Because river current is gentler than the ocean waves, river pebbles are usually not as smooth as beach pebbles. Other pebble beaches are in northern Europe (particularly on the beaches of the Norwegian Sea), along the coast of the U. Smooth, sandy yellow and cream stones combine to create a naturally warm look with gentle, curved edges.

Manufactured river rocks consist of quarried natural stone that has been artificially resurfaced on one side to resemble river rock and cut flat on the other side.Some products may be delivered straight to your door from one of our suppliers and these products will be labelled within the product description. Some of the data that are collected include the number of visitors, their source, and the pages they visit anonymously. Pebbles come in various colors and textures and can have streaks, known as veins, of quartz or other minerals. These are generally used in construction as a finish for exterior and interior walls: the flat side of the rock adheres easily to a wall base, while the shaped river rock surface gives the wall a natural, organic beauty.
