Earthquake Test
| What is an earthquake? | the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. |
| p waves, s waves, and surface waves. | |
| P waves can travel through solids, gases and liquids. They are the fastest waves. The ground squeezes and stretches in direction of wave travel | |
| Second wave two arrive. Travels through only solid. ground t motion is perpendicular to direction of wave travel. | |
| Last to arrive. Causes the most damage along Earth’s surface. | |
| How do scientists know that the Earth’s outer core is liquid? | We know that s waves do not travel through neither liquid or the outer core of the Earth . Therefore the earth,s outer core has to be liquid. |
| Focus | it is the central point of the area over which fault movement occurred and caused the earthquake. |
| Fold | A bend in a layer of rock or in another planar feature |
| a fracture or zone of fractures between two blocks of rock. | |
| The epicenter is usually the location where the greatest damage associated with an earthquake occurs. | |
| The Richter Scale is an absolute scale; wherever an earthquake is recorded, it will measure the same on the Richter Scale. Second, the Modified Mercalli scales measures how people feel and react to the shaking of an earthquake. ... It is sufficient to di | |
| What are the common causes of earthquakes? Where are they concentrated? | |
| The East Coast because it lies along a very active plate | |
| New Jersey lies near a state with a plate boundary | |
| Buildings and other structures. |
