Geological techniques are methods used by geologists to study the Earth's structure, materials, and processes. These techniques include field surveys, where geologists observe and collect samples from rock formations, and remote sensing, which uses satellite imagery to analyze land features. Other methods involve drilling to obtain core samples and geophysical surveys that measure physical properties of the Earth. Additionally, geological techniques often incorporate laboratory analysis to determine the composition and age of rocks and minerals. Techniques such as radiometric dating help establish timelines for geological events, while geochemical analysis reveals the elemental makeup of samples. Together, these methods provide valuable insights into Earth's history and resources.
