seismic stratigraphy

Seismic stratigraphy is a technique used by geologists to interpret underground layers of rock and sediment using sound waves. By sending seismic waves into the Earth and recording how they bounce back, scientists create images of the subsurface. These images help identify different geological layers, their shapes, and how they are stacked or connected over time. This information is crucial for understanding Earth's history, locating reservoirs of oil and gas, and assessing geologic hazards. Essentially, seismic stratigraphy is like a medical ultrasound for the Earth’s interior, revealing hidden structures beneath the surface.
