Passage I
Earthquakes produce seismic waves that can travel long distances through Earth. Two types of seismic waves are p-waves and s-waves. P-waves typically travel 6-13 km/sec and s-waves typically travel 3.5-7.5 km/sec. Figure 1 shows how p-waves and s-waves move and are refracted (bent) as they travel through different layers of Earth’s interior. Figure 2 shows a seismograph (an instrument that detects seismic waves) recording of p-waves and s-waves from an earthquake. Figure 3 shows, in general, how long it takes p-waves and s-waves to travel given distances along the surface from an earthquake focus (point of origin of seismic waves).
2. According to Figure 1, when p-waves encounter the boundary between the mantle and the core, the p-waves most likely:
Your Answer is
Correct Answer is G
Explanation
The solid line in figure 1 represents p-waves. At the junction of core and mantle, part of p-waves is refracted, and another part of p-wavse directly passes through core
