| What are earthquakes? | Areas where rocks slip and move past each other producing a large amount of energy |
| What is elastic deformation? | Temporary change of shape of rock as it resists movement at plate boundaries |
| What is elastic rebound? | When rock under elastic strain slip and return back to its original shape (although broken and shifted) and release a lot of energy in the process |
| Energy released in an earthquake are called? | Seismic Waves |
| This type of seismic wave is a body wave, fast and moves in and out | P Waves |
| This type of seismic wave moves through the earth, moves side to side, doesn't travel through liquid and is slow | S Waves |
| These types of waves only occur at the surface of the Earth and can produce the most damage | Surface Waves |
| A measure of seismic waves can be read on a... | seismogram |
| The difference between the s wave arrival time and the p wave arrival time is called the .... | S-P interval or lag time |
| The method for locating the epicenter of an earthquake is called... | triangulation |
| The scale that measures the intensity of shaking felt by people is called | Modified Mercalli Scale |
| The scale that measures the amount of ground motion is called the | Richter Scale |
| If the ground motion is 10 times greater than a M6 earthquake, than the earthquake will be a M? earthquake? | M7--each whole number, or magnitude, on the Richter scale is 10 times more ground motion than the number or magnitude before. |
| Magma that is viscous with high water and gas content will produce this kind of eruption. | Explosive |
| Thin, low gas content, mafic magma produces this type of volcano. | Shield Volcano |
| What type of volcano is created from alternating explosive and non explosive eruptions? | Stratovolcano |
| This type of volcano is small with steep sides. It is weathered and eroded away relatively quickly. | Cinder Cones |
| This volcanic activity happens away from plate boundaries | Hot Spots |
| Two examples of hot spot islands are.. | Hawaii and Iceland |
| This is an explosive blast of hot ash, dust and gasses. It could wipe out a mountainside very quickly | Pyroclastic Flow |
| When a volcano has an explosive eruption, it may blast a huge portion of its central vent away creating a large depression called a... | Caldera |
| Around the central vent of a volcano is often a small pit called a... | Crater |
| An area that repeatly experiences eruptions of lava that is spread out in a large area is called a | Lava Plateau |
| The body of molten rock that feeds a volcano is called a | Magma Chamber |
| Cracks in the Earth's crust where magma flows up from a magma chamber are called | Vents |
| Three types of volcanoes are | Stratovolcanoes, Cinder cones and shield volcanoes |
| This type of volcano is the largest, which broad sloping sides produced from non explosive eruptions or lava flows | Shield Volcanoes |
| Hawaii's Mauna Loa is an example of this type of volcano | Shield |
| Italy's Stomboli is an example of this type of volcano | Cinder Cone |
| Yellowstone is an example of this type of volcanic activity | Hot Spot |
| Washington's Mt. St. Helen is an example of this type of volcano | Stratovolcano |
