Estimate, to the nearest tenth of a minute, the times that P-waves and S-waves firstarrived at each recording station (seismogra
ph location) in Figure 4. Then, subtract Pfrom S to get the S-minus-P time interval: First P arrival First S arrival S-minus-P

P waves can travel through liquid and solids and gases, while Swaves only travel through solids. Scientists use this information to help them determine the structure of Earth.
S waves have a larger amplitude than P waves and cause the ground's surface to move both vertically and horizontally, making them more dangerous. Surface waves, which move slowly, are the last to arrive. P waves leave the earthquake first and go the furthest. Rock oscillates perpendicular to the direction of wave propagation in S or shear waves. In rock, S waves typically move at a pace of roughly 60% that of P waves, and they always come after the latter. Points of solid media move back and forth perpendicular to the wave's direction of propagation due to S waves, also known as shear or transverse waves. As the wave passes, the medium is sheared first in one direction and then in the opposite direction.

Metropolitian Areas are those that are developed. This answer makes the most sense because a developed area is one that people have grown in and settled.
The rapid increase in ocean heat content has led to around 19mm of sea level rise just from thermal expansion between 1993 and 2010, around a third of the total increase of 54mm.
I think the answer is plate movement. Tectonic plate movement is the movement on the lithosphere. This movement is defined into three; we have the convergent, divergent and transform. Plate movements often caused volcanic eruptions as well as earthquakes, depending on the movement on the plates.
