Question

which of the following affects the speed of a seismic wave?
a. wavelength
b. energy
c. pressure of media
d. amplitude

Explanation:

Seismic waves' speed is affected by the properties of the medium they travel through. The pressure (or density, elasticity) of the media (like rock, fluid in the Earth) influences wave speed. Wavelength, energy, and amplitude don't directly affect the speed of seismic waves; speed depends on medium properties. So the pressure of the media (option C) affects seismic wave speed.

Answer:

C. pressure of media
