Which have scientists learned from studying seismic waves that travel through earth’s interior?
DENIUS [597]
<span><span>D. They have learned the precise depths where the boundaries between the earth's layers are located.</span>

The overwhelming amount of seismic activity particularly happens along convergent plate boundaries. In particular, reverse or thrust faults occurs on convergent plate boundaries.Converging plate boundaries are classified into two types of activities.First is the subduction boundary where the oceanic lithosphere is pressured beneath a continental plate or oceanic plate thus it overrides the other plate then slowly directed to the mantle where it will become a magma. Second is the collisional boundary where earthquakes occur because of the continental crust squeezed together then plates are pushed upwards.Reverse faults are correlated to earthquakes with magnitude of 8 or more.Hence, earthquakes of magnitude 8 or more are considered powerful and mega thrust earthquakes.</span>
