What happens to P- and S- waves when they reach the center of the earth?

P waves travel much faster than S waves so they reach the core faster. They can travel through the outer core, but change direction slightly, causing a p-waves shadow zone. S waves cannot travel through the outer core because it is liquid and has zero rigidity so they are diverted around it causing a much larger shadow zone called the S wave shadow zone. Surface, or L waves cannot travel through the earth at all.
P-waves are observed directly opposite to the epicentre of earthquake which states that the wave passing through the earth as a diameter has no effect on its path.

Can secondary waves travel through the center of the earth?
No, because to reach the center of the Earth, they need to pass through the outer core. Secondary waves, or S-waves, can't pass through liquids, such as the liquid outer core, so they can't thus even reach the center of the Earth.
Why do more ultraviolet waves reach earth today?
More ultraviolet waves reach earth today because the atmosphere is changing and they do not get filtered out.
What wave type is formed when the waves reach the Earth's surface?
Surface waves
Which wave type is formed when the waves reach the Earth's surface?
s wave
How do scientists know that their is a red hot coar in the center of earth?
A man named Richard Dixon Oldham discovered that the earth has a core. He determined this by studying the propagation of seismic waves from earthquakes. He hypothesized that the seismic waves had an origin, which he believed came from the center of the earth from a molten core.

What wave type is formed when the waves reach the Earth's surface?
Surface waves
How does energy from earthquake reach earth surface?
energy reachs earth surface through seismic waves: P waves S waves and Surface waves
What happens when seismic waves move from the Earth's crust to the mantle?
Refraction Happens
What happens to S waves when they reach the liquid part of the Earth's surface?
S waves cause rocks particles to move from side to side. The rock particles move at the right angles to the direction of the waves. However liquids can not support shear stresses and therefore S waves can not propagate through them.
How does the suns energy reach Earth?
Waves of heat and light, called radiation, travel to earth.
What is the place on earth's surface that earthquakes waves reach first?
This is known as the epicentre.
Which wave type is formed when the waves reach the Earth's surface?
s wave
What happens if thunder hits earth?
Thunder is sound waves. They hit Earth all the time, and nothing in particular happens.
How does from an earthquake reach Earth's surface?
energy reachs earth surface through seismic waves: P waves S waves and Surface waves
What happens to S waves and P waves as they pass through the Earth's inner core?
its simple. they dont
