Final answer:
Seismic waves travel outward from the earthquake's focus, with the epicenter above it. These waves vary in types and speeds, bending and bouncing as they move through different materials.
Explanation:
When earthquakes occur, seismic waves spread out from the focus, with the epicenter being the surface point directly above the focus. These waves include body waves (S- and P-waves) and surface waves, each causing different motions in rocks and traveling at different speeds. The waves bend and bounce, a process known as refraction and reflection, based on the materials they encounter.
