Earthquakes occur almost faults(断层), the areas where plates meet. About 80 percent of earthquakes occur around the Pacific Occan. Called the Ring of Fire because of the large number of volcanoes there, the area is a meeting point for many plates....
Usually, the plates move smoothly. But when they suddenly move several centimeters, pressure builds up where they are pushing into or against each other, so that earthquakes happen. Almost all earthquakes happen at faults. Most of the earthquakes happen along the coast. However, some happen in ...
- You know that most earthquakes usually occur along faults located near the boundaries between plates. (Most faults near plate boundaries are not the actual plate boundary itself but rather are related to the titanic forces associated with two giant plates grinding past one another.) ...
Earthquakes usually happen on the edges of large sections of the Earth’s plates. These plates slowly move over a long period of time. Sometimes the edges, which are called fault lines, can get stuck , but the plates keep moving.Pressure slowly starts to build up where the edges are stuck...
at present dr johnson’s aspirations are limited to predicting the timing of an imminent quake. a full prediction would also need to include whereabouts along the fault it was going to happen and its magnitude. however, if ti...
1 Earthquakes,also called temblors (地震) ,can be so extremely destructive; it's hard to imagine they occur by the thousands every day around the world,usually in the form of small tremors. Some 80 per cent of all the planet's earthquakes occur along the rim of the Pacific Ocean,called...
解析 1)Because faults usually form at the edges of the plates. And when the stress that builds up in the rocks along a fault is too much, the rocks break suddenly and an earthquake takes place. 2) In case of an earthquake. 3) (Omitted.) ...
12.The movement of the Earth's crust along faults and plate margins sometimes causes ___,which have destroyed many cities and killed millions of people. A.thunders B.lightenings C.quakes D.floods 答案与解析:C 从题干前半部分“地壳沿着断层和板块边缘的运动有时可导致……”及后半部分产生 的...
Usually, the plates move smoothly. But when they suddenly move several centimeters, pressure builds up where they are pushing into or against each other, so that earthquakes happen. Almost all earthquakes happen at faults. Most of the earthquakes happen along the coast. However, some happen in ...
faults, and most of the earthquakes around the world occur on these faults. Since the edges of the plates are rough, they get stuck while the rest of the plate keeps moving. Finally, when the plate has moved far enough, the edges unstick on one of the faults and there is an ...
