Unit 3 Quiz Review
This will help you prepare for the Unit 3 quiz over the Restless Earth!
| Question | Answer |
|---|---|
| What factor is primarily responsible for the heat found inside of Earth? | radioactive decay |
| Where is the crust (lithosphere) the thinnest and most dense? | under the oceans |
| Which physical layer is plastic and soft enough to allow the tectonic plates to float on it? | asthenosphere |
| Which physical layer is the only liquid layer in the Earth? | outer core |
| What is the only seismic wave that is fast enough to travel all the way through the Earth? | P-wave |
| Who is responsible for coming up with the idea of continental drift back in the early 1900's? | Alfred Wegener |
| What four pieces of evidence were used to support the idea of continental drift? | 1. the apparent shape of the continents, 2. rock correlation, 3. fossil correlation, 4. climatic evidence in coal deposits and glacial grooves |
| What is the process by which one tectonic plate is pulled underneath another? | subduction |
| What is the strongest evidence we have to support the theory of plate tectonics & continental drift? | magnetic reversals |
| What are the three primary causes for tectonic plate motion? | convection currents, ridge push, slab pull |
| What do we call the place within Earth along a fault at which the first motion of an earthquake occurs. | focus |
| What geographic spot on Earth will have the greatest amount of shaking during an earthquake? | epicenter |
| What is a break in the Earth's crust along which blocks of rock move? | fault |
| What stresses are responsible for pulling, squeezing, and twisting rocks to a point at which they eventually break? | tension, compression, shear stress |
| What is the sudden return of rock to its original shape after elastic deformation? | elastic rebound |
| Which land form is most likely to have a normal fault? | Mid-Atlantic Ridge |
| What type of plate boundary is the San Andreas Strike-Slip Fault located on? | transform |
| What is a terrible consequence of reverse faults on the ocean floor? | tsunamis |
| Which of the following statements summarizes how the formation of the solar system was similar to the differentiation of Earth into layers? | In both processes, the densest materials moved to the center. |
| At which type of plate boundary would you likely find a reverse fault? | convergent plate boundary |
| At which type of plate boundary would you likely find a strike-slip fault? | transform plate boundary |
| At which type of plate boundary would you likely find a normal fault? | divergent plate boundary |
| Which seismic wave causes the most damage to buildings, roads, bridges, and homes? | Love wave |
| What's the shortest amount of time our planet would need for a complete magnetic reversal? | one year |
| Where will you fin the majority of earthquakes and volcanoes on Earth? | Ring of Fire around the Pacific Plate |
| Why are earthquakes & tsunamis more devastating in poor areas of the world? | Poor building materials and lack of effective warning systems |
