Geology-the study of the Earth, the material it is made of and the processes that act on them.

Geologists study some of society's most important problems, such as energy, water, and mineral resources; the environment; climate change; and natural hazards like landslides, volcanoes, earthquakes, and floods.

Sales of limestone and dolomite in Ohio in 2015, by county and quantity

​

Ohio ranks fourth in the nation in production limestone. They are quarried in 48 counties, annually producing 79 million tons valued at $471 million.

​

Most of the limestone produced in Ohio is used for construction of roads and building projects and in concrete and asphalt. Also an important source of agricultural lime, used in making steel, cement, building stone, and many uses in the chemical industry.

Limestone is needed in other areas and is so important that buyers will pay five times the value of the stone in delivery charges so that limestone can be used in their project.
