How does earth's solid inner core affect seismic waves?

Why Earth's inner core has speed trap for seismic waves. Earth has multiple layers: the crust, the mantle, the liquid outer core and the solid inner core. Something is not quite right inside the Earth's core. When seismic waves from earthquakes ripple through its solid center, they hit a speed bump. read more

About the Earth's inner core- the main way that they have to think about the inner core is by seismic waves. When an earthquake happens in one part of the world, its massive jolt sends a shock wave around the globe. This shock wave has to travel through different materials as it passes. read more

A. Only S waves travel through Earth's inner core. P and S waves can both travel through solids. B. The inner core is less dense than the outer core. This does not indicate that the inner core is a solid. C. Only P waves travel through Earth's inner core. P and S waves can both travel through solids. read more

Seismic waves contain both P waves and S waves. P waves can travel through the Earth including the inner core while S waves could not pass through the core. read more
