Explanation:
Both P and S-waves travels as body waves within the earth.
They are seismic waves. P-waves are longitudinal waves and as such can travel through any material medium. S-waves are transverse waves can only travel through solids.
- If the earth is uniformly solid, at the seismograph station, both waves would be picked.
- Based on travel time, p-waves will reach the station first before s-waves.
I think because, on a map, it looks so big, and people want to go there because of that.
Also, because there are lots of attractions there.
My last reason is because it's so hot, and maybe some people like hot.
Glad I could help, and good luck!
