Question
9. Strike-slip faults, like the San Andreas Fault, are not perfectly straight but benod gradually back and forth. In some locations, the bends are oriented such that blocks on opposite sides of the fault pull away from each other, as shown in the accompanying sketch. As a result, the ground between the bends sags, forming a depression or basin. These depressions often fill with water. a. What name is given to the depression in the accompanying photo? b. Describe what would happen if these two blocks began moving in direction:s 10. Using the Internet, compare and contrast the 2010 Hait earthquake with the 2011 Japan earthquake. Include magnitude, type of plate boundary, and extent of destruction. Explain why the Japan earthquake produced a tsunami, while the Haiti quake did not. 11. Describe the two different ways that Earth's layers are defincd 12. Based on the properties of Earth's layers and the mode of travel of body waves, Michael Colier predict the location in Earth's interior where waves should (a) travel fastest and (b) travel slowest. Is there an exception for these generalities? Explain your answers. Extansion and Before offset After offset EXAMINING THE EARTH SYSTEMExplanation / Answer
9.a > what name is given to the depression in the accompanying photo ?
Answer :
The fresh water body collected in the lowest part of a depression which formed in between two side of an active strike slip fault is called sag pond . This depression zone is normal fault or transtensional zone . The transtension means that extension is a deformation component of bulk strike slip faulting
9.b> Describe what would happened is these two block begun moving in opposite direction ?
Answer :
If those two block begun to moves in opposite direction that is when those plates are diverging from each other then extension occurs between two block and normal fault generate . As time increases , the distance between them gradually increases and magma comes out to the surface from asthenosphere and also few shallow earthquake will be present due to normal faulting .
