Changing in rocks happens as a result of natural processes that are taking place all the time. Most of the changes happen very slowly. Rocks that are in the deep within the Earth are right now becoming other types of rocks. Rocks at the surface are lying in place before they are next exposed to a process that will change them to another rock. Even at the surface, we may not notice the changes in the rocks.
