geological cross-sections
A geological cross-section is a diagram that shows a vertical slice through Earth's layers, revealing the arrangement and types of rocks beneath the surface. It helps us visualize what lies underground, including faults, mineral deposits, and different rock formations. These sections are created using data from drilling, rock samples, and seismic surveys. By studying cross-sections, geologists can understand how Earth's structures formed, locate resources, and assess hazards. They are valuable tools for interpreting the unseen underground world in a clear, detailed way, connecting surface features with the hidden geology beneath our feet.
