Deep Earth Science is the study of the Earth's interior, focusing on its structure, composition, and processes. This field explores layers such as the crust, mantle, and core, using techniques like seismic wave analysis and mineral studies to understand how these layers interact and influence geological phenomena. Researchers in Deep Earth Science also investigate the origins of volcanoes, earthquakes, and the movement of tectonic plates. By examining these processes, scientists can gain insights into the Earth's history and its dynamic systems, which are crucial for understanding natural hazards and the planet's evolution over time.
