Final answer:
Short-period (SP) waves are seismic waves that typically have periods of 0.02 to 0.06 seconds and are associated with magma rising towards the surface.
Step-by-step explanation:
Seismic waves that typically have periods of 0.02 to 0.06 seconds and are associated with magma rising towards the surface are short-period (SP) waves.
Short-period (SP) waves are a type of seismic wave that have higher frequencies and shorter periods compared to other seismic waves. They are primarily generated by shallow earthquakes and volcanic activity, such as magma movement and volcanic explosions.
These waves are useful in monitoring volcanic activity and can provide valuable information about the movement of magma beneath the Earth's surface.
