How is Limestone obtained? Is it mined or extracted?

Answer 1

Limestone is a sedimentary rock made from the shells of sea creatures which died and sank to the bottom. If you look at it with a magnifying glass you'll see sea shells, and sometimes larger fossils. So wherever limestone is found it was once underwater. It is mostly calcium carbonate. Limestone is mined. You need to break it up and scoop it out. Most parts of the world have some limestone, even inland places like Kansas, which was once a sea, and mountain ranges, which were once underwater and were pushed up by plate tectonics.

Answer 2

Limestone is mined. The cheapest way to get it is to use the limestone rock closest to the surface. Most commonly, that involves quarrying, in which you dig a hole and build a road for trucks to carry the rock out.

A lot of limestone gets used, so there are many quarries, wherever limestone is at or close to the surface.

Answer 3

In some way, the first bacteria and one-celled plants learned to take lime (CaCO3) from the water; they collected in jelly-like masses. Lime collected on these early plants, layer upon layer, and built up into great masses of limestone. Later, when animals came upon the earth they were also one-celled creatures living in the sea, but as they struggled for existence they evolved to more complex creatures, and in time they also took lime from the sea water to make protecting external coverings or shells. When these creatures died their shells fell to the sea floor, accumulated in thick masses, were also broken to lime muds, but all in time became limestone rock – the cemeteries of the animals which lived in the seas, and the museums in which the records of past life (fossils) are preserved.

Answer 4

i know that limestone is found in fossils....its what makes up the fossilized imprint i remember from my geo class..
