Earthquake Waves

1.These waves are the fastest waves. 2.These waves travel through anything. 3.These waves are secondary waves. 4.This is the place inside the Earth where the Earthquake actually occurs. 5.This is the place on the surface of the Earth directly above the Earthquake location. 6.These are surface waves & are very slow. 7.These are only half as fast as primary waves. 8.Where do the deepest Earthquakes occur? 9.These waves are compressional waves.

10.We are confident in our knowledge of the structure of the Earth. We know that it has a Crust, Mantle, Outer and Inner Core. This information has been determined using ________________. 11.Geologists working in the coalfields of Southwest Virginia have be able to determine vital information about sub- surface(several thousand feet). They are interested in where one would find coal seams to mine. Their information comes from ____________________.
