What fields does the study of Natural Sciences primarily encompass?

The study of Natural Sciences primarily encompasses fields that focus on understanding the natural world through observation, experimentation, and empirical evidence. Chemistry and physics are two foundational disciplines within the natural sciences. Chemistry studies the composition, structure, properties, and changes of matter, while physics deals with the fundamental principles governing the behavior of energy and matter. Together, they form a comprehensive framework for understanding various phenomena in the natural world, making them core components of the Natural Sciences.

Biology, while also a crucial part of the natural sciences, is specifically the study of living organisms and their interactions with one another and their environments, which is why it is not included in the correct answer in this context. The other combinations mentioned include disciplines that, although related to natural sciences, may not provide the same breadth of fundamental principles as chemistry and physics do together. Thus, focusing on chemistry and physics represents a holistic understanding of the natural laws that govern various scientific phenomena.
