Key Differences

Geologic is an adjective that refers specifically to Earth's physical structure, processes, and history. It often focuses on the aspects that deal with the solid Earth, such as rock formations, tectonic movements, and the layers that make up the planet's crust and upper mantle. On the other hand, geological encompasses a broader spectrum, including not just the solid Earth but also the role of water, climate, and biological activity in shaping the Earth's surface and crust.
When discussing geologic time scales, the term emphasizes the division of Earth's history into eras, periods, and epochs based on significant events in the planet's physical development. Meanwhile, geological studies might also consider how these time periods relate to the development of life, the atmosphere, and the oceans, integrating a wider range of scientific disciplines including paleontology and climatology.
Geologic features primarily include those related to the structure of the Earth itself, like mountains, volcanoes, and earthquakes. Geological features, while including these, also extend to include formations and phenomena influenced by life, water, and atmospheric conditions, such as sedimentary rock layers rich in fossils, or landscapes shaped by glaciation.
In terms of research and application, geologic analysis might focus on understanding natural hazards, mineral and energy resources, and the stability of structures on the Earth's surface. Geological research, while also concerned with these areas, tends to incorporate a more interdisciplinary approach, including the study of how Earth's systems interact over geologic time to influence the environment and climate.
Both geologic and geological perspectives are crucial in environmental science, natural resource management, and climate change studies. However, the emphasis of geologic work is more on the Earth's physical properties and history, whereas geological studies tend to adopt a more holistic view, considering the interaction between the Earth's geology and its biological, hydrological, and atmospheric systems.
