Core sampling is a technique used to collect cylindrical sections of soil or rock, known as cores, from the ground. This method allows scientists and engineers to analyze the physical and chemical properties of subsurface materials. Core samples are essential for understanding geological formations, assessing natural resources, and evaluating environmental conditions. The process involves drilling into the earth using specialized equipment, which extracts a core that retains the original structure of the material. Core sampling is commonly used in fields such as geology, mining, and environmental science to gather data for research, construction projects, and resource management.
