Question: Describe the different types of seismic waves and how they are measured?
Seismic waves are the energy waves that travel through the Earth's layers, and they are typically measured using a seismograph. There are two main types of seismic waves: body waves and surface waves. Body waves include Primary (P) waves, which are compressional waves that can travel through both solid and liquid layers, and Secondary (S) waves, which are shear waves that only move through solid materials. Surface waves travel along the Earth's exterior and include Rayleigh waves, which move in a rolling motion, and Love waves, which shake the ground side to side. Seismographs measure these waves by recording the ground motion at different locations, allowing scientists to determine the location and magnitude of earthquakes.
