According to the text, what does geology primarily study?

• A. The internal mass of the Earth.
• B. The outer layers and composition of the Earth.
• C. The history of all geological events.
• D. The study of celestial bodies that influence the Earth.

Answer: (B)

Geology primarily focuses on understanding the outer layers and composition of the Earth, which includes its structure, materials, and the processes that shape its surface. This encompasses the study of rocks, minerals, soil, and the various physical and chemical processes that affect these components. Option B is the most comprehensive in capturing the essence of geology, which not only examines the Earth's outer layers but also how these layers interact and evolve over time. This is crucial for understanding natural phenomena like earthquakes, volcanic activity, and erosion, as well as the resources Earth provides. Other options reflect more narrow aspects of geological study. For instance, while the internal mass of the Earth is certainly an important area of geophysics, it is not the primary focus of geology. The history of geological events is a significant part of the discipline, but it doesn’t encompass the full study of the Earth's current layers and their compositions. The study of celestial bodies may be related to earth sciences, but it falls under astronomy rather than geology specifically. Hence, the correct answer captures the core focus of geological study comprehensively.
