This animation looks at a basic physical comparison of the Earth with our closest neighbor, Mars. In 2018, InSight put an IRIS seismograph on Mars. Why would we do that? The purpose is to study that planet's deep interior by monitoring any earthquakes that are generated and using the information to determine a general picture of what lies below the surface. It quickly answered the question, "does Mars have earthquakes?" It does. Is it a layered planet like Earth? How thick are the layers?

$Seismic Waves Travel Curving Path Thru Earth (Educational) Seismic waves travel a curving path through the earth due to changes in composition, pressure, temperature within the layers of the Earth. If there were no changes with depth, seismic waves would travel a straight path to the other side of the Earth. But wave arrivals to distant seismic stations have taught us that there are layers. Seismic waves through the Earth follow the same laws of refraction and reflection as any other wave at interfaces. When they encounter boundaries between different media, the wave will react according to Snell’s law, and the angle of refraction across the boundary will depend on the velocity of the second media relative to the first.
