Limestone is a carbonate sedimentary rock consisting of primarily of calcium carbonate (CaCO 3 ). Ohio limestones were deposited in warm, clear, shallow inland seas that covered the state during most of the Paleozoic Era. Many are highly fossiliferous, being comprised in large part of the remains of ancient marine organisms such as calcareous ...

Carbon is an element that is essential to all life on Earth. Carbon makes up the fats and carbohydrates of our food and is part of the molecules, like DNA and protein, that make up our bodies. Carbon, in the form of carbon dioxide, is even a part of the air we breathe. It is also stored in places like the ocean, rocks, fossil fuels, and plants.
