Question

Once again you will be studying the fictional planet Zorgon. which is known to have a crust, mantle, and core-just like Earth. Based on the following observations, estimate the composition of the Zorgonian crust, mantle, and core. Samples readily available on the surface have the chemical composition given by in Table 1 Volcanoes on Zorgon originate in the mantle and produce lavas with a typical chemical composition given m Table 1. Volcanoes on Zorgon occasionally bring up xenoliths, and three representative samples are shown in Table 1. The P-wave velocity of the Zorgon crust Is approximately 4 5 km/s. The P-wave velocity of the Zorgon mantle is approximately 5.5 km/s. The P-wave velocity of the Zorgon core is approximately 10 km/s The S-wave velocity in the Zorgon core is 7 km/s An ophiolite located on the island of BhomiRoku exposes two types of rock, one overlying the other. Both compositions are given in Table 1. Zorgon has no magnetic field. The average density of the Zorgon, determined from planetary motions, is 4.000 kg/m^3. Two types of meteorites have been collected on Zorgon, Type A and Type B Both composAons are given m Table 1. Based on these observations, estimate the composition of the three compositional layers on Zorgon: Do you think Zorgon has a liquid core? What is your evidence?

Explanation / Answer

Crust: From the given seismic velocity of seismic wave it is clear that the crust is liquid.

Mantle: Mantle is also liquid with low velocity of seismic wave.

Core: Since, seismic wave velocity is more, core is thought to be solid.

Since, both core and mantle are with liquid composition, core is solid. Hence, Zorgon has no liquid core.
