1. Airborne soot and dirt from the impact blanketed Earth, inhibiting photosynthesis and triggering mass extinction of species. 撞击产生的烟尘和灰尘覆盖了地球，抑制了光合作用，引发了物种的大规模灭绝。
2. According to the stress-triggering hypothesis, faults are unexpectedly responsive to subtle stresses they acquire as neighboring faults shift. 根据应力触发假说，当相邻断层移动时，断层会意外地对它们获得的细微应力作出反应。
3. In accordance with the stress-triggering hypothesis, faults are unpredictably responsive to subtle stresses they obtain as neighboring faults shift. 根据应力触发假说，断层不可预测地对邻近断层移动时所获得的微妙应力作出反应。
4. The unprecedented land clearance released vast quantities of carbon dioxide into the atmosphere, triggering for the first time humanly caused global warming. 空地的规模史无前例，它们将大量的二氧化碳气体释放到了大气中，因而引发了第一次人为导致的全球变暖。
5. This is not surprising, given that precipitation is one of the two external triggering mechanisms—the other being seismic activity—involved in the formation of landslides. 考虑到降水是涉及滑坡形成的两个外部触发机制之一——另一个是地震活动，这并不奇怪。
