The discussion confirms that the planet's core is solid based on the observation of S waves from seismic activity. S waves, or secondary waves, can only propagate through solid materials, which directly indicates that the core cannot be liquid or gaseous. The conclusion is supported by theoretical equations related to wave propagation in different states of matter.
PREREQUISITESSeismologists, geophysicists, and students studying Earth sciences who are interested in understanding planetary core composition and seismic wave behavior.
Please justify your answer with Relevant Equations and show your work. Thank you.cooltu said:Homework Statement:: Suppose that space traveling seismologists observe S waves from a quake origination on the far side of a planet . What does this tell them about core?
a) It is solid
b) it is liquid
c) it is gaseous
d) it is fluid
Relevant Equations:: theoretical
It is solid
