I want to know the answer to the following question:
In the 18th century, what changed geology drastically?
All the background I'm provided with is that "Aided by chemical experimentation, naturalists such as Scotland's John Walker, Sweden's Torbern Bergman, and Germany's Abraham Werner created comprehensive classification systems for rocks and minerals—a collective achievement that transformed geology into a cutting edge field by the end of the eighteenth century.". Is that enough to answer the question?
