Cobbles And Boulders

Cobbles and boulders are two types of sedimentary rocks that are commonly found in riverbeds, beaches, and other areas where water flows or has flowed in the past. Cobbles are smaller than boulders and are generally defined as rocks that are between 64 and 256 millimeters in diameter. Boulders, on the other hand, are larger than cobbles and are defined as rocks that are larger than 256 millimeters in diameter. Cobbles and boulders are formed through a process called weathering, which is the breakdown of rocks and minerals due to exposure to the elements. This process can occur through physical, chemical, and biological means, and can result in the formation of rocks of various sizes and shapes. Cobbles and boulders are typically formed through the physical weathering of rocks, which involves the breaking down of rocks into smaller pieces through processes such as freeze-thaw cycles, abrasion, and impact. Cobbles and boulders are important components of river ecosystems, as they provide habitat for a variety of aquatic organisms. They also play a role in shaping the physical characteristics of rivers, as they can influence the flow of water and the formation of rapids and eddies. In addition, cobbles and boulders are often used in landscaping and construction projects due to their durability and aesthetic appeal.
