A "low seismic velocity" zone is located at about 100-350 km within the Earth. This is a weak, easily-
deformed, and flowing zone of plastic rock in which seismic waves slow considerably. What is the name of
this zone?

The Earth's crust is primarily composed of silicate-rich rocks. What are the two most common elements in
the crust?
When an earthquake occurs, no S-waves are detected on the opposite side of the Earth, providing evidence
that the outer core is molten. This phenomenon is called:

Mohorovicic Discontinuity
shadow zone
low velocity zone
seismic gap
