Explain the Different Types of Seismic Waves

Plate tectonics is the scientific theory explaining the movement of the earths crust. Until recently it has been necessary to use different seismometers sensitive to different frequency ranges and with varying ground-motion amplification to record the different wave types.

As seismic waves pass through the Earth they are refracted or bent like rays of light bend when they pass through a glass prism.

. Because the speed of the seismic waves depends on density we can use the travel-time of seismic waves to map change in density with depth and show that the Earth is composed of several layers.

Therefore the various types of instruments intrinsically tend to record only those types of waves with corresponding periods which may represent only a small part of the total ground.

Recall that both continental landmasses and the ocean floor are part of the earths crust and that the crust is broken. It is widely accepted by scientists today.
