In this lesson, students learn about different types of seismic waves on the basis of where and how the waves move. In addition, students discuss how scientists use earthquake waves to investigate ...

A recording of an earthquake has recognizable characteristics. Typically, one can recognize the arrival of different wave types. The P waves (the fastest traveling waves), S waves, and Surface waves ...

The greater the number, the larger and more powerful the earthquake. Live updates: 4.8 magnitude earthquake rattles NYC, New Jersey There are four types of ... seismic waves which lead to an ...

The core itself consists of a solid inner core and a liquid outer core. There are three types of seismic waves – P waves, S waves and surface waves. P waves are longitudinal waves, and their ...

When the waves cross the boundary between two different layers ... It is the slowest of the three types of seismic wave. Surface waves usually have larger amplitude than the other waves and ...

There are a number of ways to measure the magnitude of an earthquake. Most scales are based on the amplitude of seismic waves recorded on seismometers ... This 8 minute video uses the analogy of a ...
