A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

To aid in their study of the earth, geologists group rocks into three categories based on their origin: igneous, sedimentary, and metamorphic. Each category is then further subdivided. About 27,000 years ago, lava flowed on top of the Navajo Sandstone, forming black “ropey” basalt in Snow Canyon State Park, Washington County.
