The Rock Cycle - digitalatlas.cose.isu.edu

Like most Earth materials, rocks are created and destroyed in cycles. The rock cycle is a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. All rocks are made up of minerals. A mineral is defined as a naturally occurring, crystalline solid of definite chemical composition and a characteristic crystal structure.

Limestone - Wikipedia

Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).A closely related rock is dolomite, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2.

Sedimentary rock - Wikipedia

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment ...

Limestone: The Calcium Carbonate Chemical Sedimentary Rock

Marble is a carbonate rock, usually a marine limestone, that has been squeezed and deformed like plastic by great heat and pressure deep beneath the Earth's surface. This process is called "metamorphism." There are also rare "igneous" carbonate rocks that have crystallized from molten magma in the same way that lavas or granites have.
