Part of the EASP Geology Walk Limestone is a popular material to use in the construction of buildings. Its weight prevents it from being used in construction of extremely tall buildings, but it is easy to cut into blocks and will stand up well to exposure. Indiana is the source of most of North America’s limestone. Granite is also a popular construction material, but it is used mainly in items such as flooring tiles, kitchen counters, and monuments. Granite can be made into a wide variety of styles, giving the person working with granite the ability to choose what looks and works best for his or her project. It is also scratch-resistant, making it useful for countertops. Department of Earth, Atmospheric, and Planetary Sciences
