There are two main types of weathering: mechanical and chemical. Mechanical weathering is the creation of sediment through physical means. For example, a stream can dislodge soil particles from its banks. Chemical weathering is the creation of sediment through chemical means. For example, acid rain can react with rocks, dissolving them.

Main Uses of Limestone In Missouri, limestone of all kinds is used mainly for aggregate (aka "gravel") that is produced by crushing and screen-sizing limestone quarry rock. The aggregate is used in concrete, for road surfacing (with or without asphalt or tar binder), and for foundation support beneath weight-bearing structures.
