Which type of seismic wave is a body wave that compresses and dilates the rock in the direction the wave is traveling, being the fastest-moving seismic wave?

💡 Solution & Explanation

Primary waves or P-waves are compressional body waves that travel faster than any other seismic waves, pushing and pulling the ground in the direction of wave propagation. Secondary waves are transverse and slower, while surface waves like Rayleigh and Love waves travel only along the Earth's crust.
