Geological evidence refers to the information, data, and observations gathered from rocks, minerals, fossils, sediments, and other Earth materials that provide insights into the history and processes of the Earth's geological past. This evidence is used by geologists and other scientists to reconstruct the Earth's ancient environments, climate changes, tectonic activities, and evolutionary processes. Geological evidence can include the analysis of rock layers, isotopic dating techniques, mineral composition, fossil records, and geological formations, among others. This field of study plays a crucial role in understanding Earth's history and predicting future geological events.
