The Great Rift Valley of Africa is the longest rift Your IP: 5.39.85.48 The most geophysically interesting feature of both models is the predicted postearthquake diffusion-like spread of strain from the plate-bounding fault into the interiors of the adjacent plates. 1. It is It is around 100km thick. boundaries. This thickening occurs by conductive cooling, which converts hot asthenosphere into lithospheric mantle and causes the oceanic lithosphere to become increasingly thick and dense with age. John Tuzo Wilson recognized that the offsets of oceanic ridges by faults do not follow the classical pattern of an offset fence or geological marker in Reid’s rebound theory of faulting, from which the sense of slip is derived. Along the third type of plate boundary, two plates move laterally and pass each other along giant fractures in Earth’s crust. Most of the damage from earthquakes is caused by: a. Earthquake is caused due to plate tectonics and normally occurs at the faults-the thin zone where there are broken rocks leading to separation of the crust. In this case, the central block is not The most common type of transform fault occurs along fracture zones and connect two divergent plate boundaries at the crest of the mid-oceanic ridge.
