Geological structure refers to the arrangement and organization of rocks and sediments within the Earth's crust. This includes features such as faults, folds, and rock layers, which are formed through various geological processes like tectonic activity and erosion. Understanding these structures helps geologists interpret the history of the Earth and locate natural resources. The study of geological structures is essential for fields like petroleum geology and mining, as it aids in identifying where valuable resources may be found. Additionally, knowledge of these structures is crucial for assessing natural hazards, such as earthquakes and landslides, which can impact human safety and infrastructure.
