Seismic waves, generated by natural events like earthquakes or artificial sources, travel through the Earth's interior and are affected by different materials and structures they encounter. By analyzing the speed, direction, and behavior of these waves, scientists can infer the composition, density, and state of the Earth's inner layers. Variations in wave propagation reveal boundaries between different layers, such as the crust, mantle, and core. This method has provided critical insights into the Earth's internal structure, which cannot be directly observed.
