All natural stone products have a very long technical life, and their actual lifetime is limited by cityscape changes or the buildings they are situated in. There are examples of natural stone products more than 500 years old in churches. WebRocks are cycled through various forms in what is called the rock cycle, a set of natural processes that form, break down, change, and re-form rocks over time. Temperature, pressure, and changes in environmental conditions at and beneath Earth’s surface drive the rock cycle. As a result of the cycle, each type of rock can change into other types.
