How is limestone rock formed.
Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as " mudstones ." Shale is distinguished from other mudstones because it is fissile and laminated.

One of the most common rocks in Kansas, limestone is a sedimentary rock composed mainly of the mineral calcite, which is a calcium carbonate. Most limestone layers formed from marine sediment deposited on sea floors, although some formed in freshwater lakes and rivers and even on dry land. Sources for the calcite in limestone include seashells.
An example of this is deposits of gypsum or halite (table salt) which often form in the desert after rain. Another example of a chemical sedimentary rock is limestone.

Limestone is a sedimentary rock, formed by the settling and consolidation of deposited materials. Sedimentary rocks are formed from deposits of material which has originally come from living organisms (chemical/organic sedimentary rocks) or from material derived from weathering and erosion of older rocks (clastic sedimentary rocks).Limestone is made up of calcium carbonate (fizzes with acid). This may be shell fragments, mud, or small, round ooliths that form in tropical lagoons. Chalk is a soft white limestone made from the microscopic skeletons of marine plankton.Even rocks, a seemingly constant substance, can change into a new type of rock. Rocks that undergo a change to form a new rock are referred to as metamorphic rocks. In the rock cycle, there are three different types of rocks: sedimentary, igneous, and metamorphic. Sedimentary and igneous rocks began as something other than rock.Different rocks have different characteristics because of their minerals, the ways in which the rocks were formed, and the processes that acted on the rocks since they were formed. ...

How is limestone formed in the rock cycle? Limestone is formed in two ways. It can be formed with the help of living organisms and by evaporation. The second way limestone is formed is when water containing particles of calcium carbonate evaporate, leaving behind the sediment deposit.As this weak acid soaked downward, it dissolved some of the calcium in the shells, producing calcium carbonate, which solidified in lower layers, much like how flowstone and stalactites are formed in caves. This material "glued" the shell fragments together into a porous type of limestone we now call coquina, which is Spanish for "tiny shell".Non-clastic sedimentary rocks limestone (left) and coquina (right). 2. METAMORPHIC ROCKS – are rocks that form through the transformation of pre-existing rocks (igneous, sedimentary, or metamorphic rocks) through the process of metamorphism. Metamorphism can involve changes in the physical and chemical
It usually forms in clear, calm, warm, shallow marine waters.
