A "földtani" refers to geological aspects related to the Earth's structure, composition, and processes. It encompasses the study of rocks, minerals, and the forces that shape the planet over time. This field helps us understand natural phenomena such as earthquakes, volcanic activity, and the formation of mountains. Geologists, the scientists who study földtani, analyze various layers of the Earth to uncover its history and predict future changes. They use tools like seismic surveys and rock samples to gather data. Understanding földtani is crucial for resource management, environmental protection, and assessing natural hazards.
