It describes how the inertial mass behaves in seismometers (correct) This is a diagram of a seismograph. During an earthquake, which part does not move with the ground? A What is the "focus" of an earthquake? It is the spot, normally below the surface, that first moves when an earthquake takes place. What is the "epicenter" of an earthquake? It is the spot at the surface, directly above the focus. This is a diagram of an earthquake made by a seismograph. At which point are the L waves recorded? D

What is the relationship between a fault plane and a fault scarp? A fault scarp is the surface expression of movement along a fault plane. The fastest travelling earthquake wave is the P wave This earthquake wave travels like a sound wave. P This earthquake generated wave produces a vertical rolling motion at the surface. R WAVE This body wave does not travel through liquids. S WAVE What is the P wave shadow zone? It is an area on the surface of the Earth that does not receive direct P waves from an earthquake How do geologists know that a portion of the core (outer core) is liquid? S waves are absorbed in this area. How are R waves used to explore the Earth's interior? They are not. In which of the following materials will P waves have the greatest velocity? granite What type of earthquake wave caused the collapse of the Nimitz Freeway in Oakland, CA during the 1989 earthquake?
