Yes, Limestone is a sedimentary rock. It can be
formed in two ways with the help of living organisms and by evaporation. Limes tone
formations with the help of living organism make us to think, like how it may form.
In brief, ocean dwelling, this is one kind of fishes such as oysters, clams, mussels and coral uses calcium carbonate to create shells and bones. All these shells and bones collectively compacted under ocean for many years to create as limestone.
Other way of formation, limestone when water containing particles of calcium carbonate evaporate. Following of sediment deposition, the water pressure dense the sediment, creating limestone. The color of the limestone depends on the other sediments in the mixture besides the minerals. Minerals are also present in the limestone and affects the color.
Fossils appear in limestone, because when something dies and its remains stay in the same place, sediment builds up on top of it, and eventually, the print of the dead thing is left in the hardened sediment (which has turned to limestone).
Limestone is formed when sediments made of calcium carbonate are buried by many subsequent sedimentary layers and compressed. Minerals crystallising out of solution bind the grains together. Sometimes the grains are formed by evaporation and sometimes they are the remains of the exoskeletons of sea creatures.
The dead organisms get trapped in the layers of sediment that then compact over a long time period, which traps the fossils:D
Chemical limestone can form when calcite is dissolved.

If you have a small sample bottle of dilute hydrochloric acid, the limestone will fizz as it is calcium carbonate and will dissolve in the acid, releasing carbon dioxide gas. The same acid will not react with the inert silica of a black chert. Sometimes chert and limestone are finely inter-bedded and the acid will pick out the limestone bands!
Yes. It is found in rocks, and has the chemical formula CaCO3 . It's a form of limestone.
dolomitic limestone is different from agricultural or hydrated limestone the difference is in the MgO content and hardness Dolomitic Limestone is harder than both and its MgO content is higher. The CaO is lower in Dolomitic limestone and High in the later.
Limestone caves are formed through a process called karstification, where rainwater picks up carbon dioxide from the air and soil, creating a weak carbonic acid. This acidic water dissolves the limestone rock over time, creating underground cavities and passages. As the water drains away, it leaves behind caves and unique formations such as stalactites and stalagmites.
Chemical limestone can form when calcite is dissolved.
it rains and sinks into limestone and over to starts to corrode at the vulnerable limestone
Marble is one form of metamorphosed limestone.
limestone forms from skeletons and shells
Limestone can be formed partly or mostly by visible shell fragments. .
Although limestone can form into other types of metamorphic rock, the most common form is marble.
Limestone - sedimentary deposition of calcarious marine organisms. Marble - compressed (metamorphosed) limestone.

Grikes form when limestone is dissolved by water.
The hard and huge mountains are known as lime stone pillars.
Chert, a form of quartz, can form as beds or nodules in limestone or dolostone.
