Core Sampling
Core Sampling is a fundamental method used in geological work to understand what's underneath the Earth's surface. Think of it like taking a vertical slice of cake - workers use special drilling equipment to extract cylindrical pieces of rock and soil from deep underground. These samples help companies determine what minerals or resources are present, how stable the ground is for construction, or where to drill for oil and gas. It's similar to how a doctor takes a biopsy to examine tissue, but on a much larger scale for examining the Earth.
