There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle. Sedimentary Rocks Sedimentary rocks are formed from pieces of other existing rock or organic …

This biochemical extraction and secretion is the main process for forming limestone, the most commonly occurring, non-clastic sedimentary rock. Limestone is mostly made of calcite (CaCO 3) and sometimes includes dolomite (CaMgCO 3), a close relative. Solid calcite reacts with hydrochloric acid by effervescing or fizzing.

These types of limestone, described in more detail below, are biochemical sedimentary rocks. Limestone is often light to dark gray, or tan, and it can be scratched by a penny. Limestone is composed of calcium carbonate (calcite, (CaCO 3) and dolomite (CaMg(CO 3) 2). This rock will strongly fizz when exposed to dilute hydrochloric acid.

Limestone is a sedimentary rock that is composed primarily of calcite. It forms from both the chemical precipitation of calcium carbonate and the transformation of shell, coral, fecal and algal debris into calcite during diagenesis.
