Which of the following is a characteristic of P-waves? a. They travel slower than other seismic waves. b. They displace the rock back and forth in a direction that is perpendicular to their travel direction. c. They compress and then expand the rock in the direction the wave travels. d. They cannot be recorded on seismographs. e. They are generated near the surface and only compress the rock as they travel.

P-waves are defined as a type of seismic wave and are known as the primary waves, and as this wave moves it contracts and expands the rock matters in its direction of propagation. This wave travels at a much faster speed and reaches the seismic station first compared to the S-waves. This P-waves carry energy in the interior of the earth as it propagates in a particular direction. The velocity of P-wave ranges from 4 to 8 km/sec. It can travel in both the solid inner core, liquid outer core, mantle, and the crust. Its speed varies with the changing density of the layers.

Thus, the correct answer is option (C).

P-waves are a form of seismic wave known as the main waves, and as they move, they constrict and expand the rock matter in their propagation path. Option C is the correct answer.

What are the characteristics of P-waves?

In comparison to S-waves, this wave travels at a significantly faster rate and arrives at the seismic station first.

As they spread in a specific direction, P-waves convey energy in the interior of the earth.

P-waves have velocities ranging from 4 to 8 km/sec.

It can move through both the solid inner core and the liquid outer core, as well as the mantle and crust.

Its speed is affected by the density of the layers.
