Geology and Exploration Geophysics are interconnected fields that explore the Earth’s structure, composition, and processes, both on and below its surface. Geology focuses on studying the materials that make up the Earth, the processes that act upon them, and the history of the planet. Exploration Geophysics, on the other hand, uses physical methods to detect and analyze subsurface features, often for the purpose of locating natural resources like oil, gas, minerals, and groundwater. Together, these fields provide essential insights for resource management, environmental protection, and understanding the Earth’s dynamics.
