Answer 1

According to the Earth sceince reference tables, which zone of Earth has the greatest density?

Inner core (more dense because of intense heat and pressure more so than outercore)

Actual point along a fault where slippage occurs and causes eqs is called an

Focus
(Epicenter- is the point on the surface nearest to the EQ (above the focus))

Which earthquakes travel through the earth's mantle?

P-waves and S-waves
Both s & p waves can pass through the mantle, however s waves cannot pass through the outer core. Only p waves can do this.
