Limestone – iDesignWiki

Limestone can also form through evaporation.Stalactites, stalagmites, and other cave formations (often called " speleothems ") are examples of limestone formed through evaporation a cave, droplets of water seeping down from above enter the cave through fractures or other pore spaces in the cave ceiling.There they might evaporate before falling to the cave floor.

How Limestone is formed

2017-5-25 · Limestone is a sedimentary rock, which means it was formed from the pile up of small rock particles that have been gathered by pressure. Coral, oysters, shell, algae, mussels and some other organisms living in the ocean use calcium carbonate (CaCO3) found in seawater to produce their bones and shells. Whenever these organisms die, their shell ...
