Which of the following scientists contributed to the classification of rocks?

The classification of rocks has a long history, with several scientists making significant contributions to the field. The correct answer indicates that all listed individuals contributed to this scientific area.

One prominent figure is Werner, who is notable for his work on the classification of rocks in the late 18th century. He proposed the theory of the geological column and was pivotal in developing a system for classifying rocks based on their origins and characteristics.

While the other names might be less well-known in the context of rock classification specifically, they still played roles in the broader development of geological sciences. The classification of rocks often draws from insights across various scientific disciplines, including geology, mineralogy, and petrology. Since all mentioned scientists contributed to advancing the understanding of geological materials and rock types in some capacity, the inclusive answer recognizes their collective contributions. Thus, selecting the choice that includes all of them acknowledges the collaborative nature of scientific advancements in rock classification.
