How can limestone form?

Answer 1

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.

Answer 2

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).

Answer 3

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.

Answer 4

The dead organisms get trapped in the layers of sediment that then compact over a long time period, which traps the fossils:D

Answer 5

It turns into marble too.
