What does geology primarily study according to the text?

• A. The structure and composition of the Earth's outer layer
• B. The mass and inner structure of the Earth
• C. The impact of human activity on the Earth's crust
• D. The growth of the Earth's atmosphere

Answer: (A)

Geology primarily focuses on the structure and composition of the Earth's outer layer, which includes the study of rocks, minerals, and the various processes that form and alter them over time. This field examines how these materials and processes contribute to the Earth's landscapes and environments. By understanding the Earth's outer layer, geologists can gather insights into its history, the processes that shape it, and the various natural phenomena that occur. The emphasis on the outer layer distinguishes this choice as the correct one, as it encapsulates the core interests of geological study, such as tectonic activity, erosion, and weathering, which directly relate to the Earth's surface. Other options, while related to Earth's features, either focus on aspects that fall outside the primary scope of geology or pertain to specific environmental studies.
