Is it true that tsunami are triggered by earthquakes originating deep beneath the ocean floor?
True
Old ocean floor is destroyed and absorbed by the Earth and remelted beneath what?
Old ocean floor is destroyed and absorbed by the Earth at subduction zones, where tectonic plates collide and one plate is forced beneath the other. The remelting occurs beneath volcanic arcs, where the subducted crust melts and rises to the surface as magma, leading to the formation of new crust.
Earthquakes that originate beneath the ocean floor produce huge tidal waves called .?
tsunami
