Geological structures refer to the various features and formations within the Earth's crust that have been shaped by geological processes such as tectonic activity, erosion, and deposition. These structures can include faults, folds, fractures, joints, and sedimentary layers, among others. Studying geological structures helps scientists understand the history of the Earth and how it has evolved over millions of years. By analyzing these structures, researchers can also identify potential natural hazards such as earthquakes and landslides, as well as locate valuable mineral resources. Additionally, geological structures play a key role in the formation of landscapes and the distribution of natural resources.
