A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include firestorms, duststorms, floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, storms, and other geologic processes. A natural disaster can cause loss of life or damage property, and typically leaves some economic damage in its wake, the severity of which depends on the affected population's resilience and on the infrastructure available. An adverse event will not rise to the level of a disaster if it occurs in an area without vulnerable population. In a vulnerable area, however, such as Nepal during the 2015 earthquake, an adverse event can have disastrous consequences and leave lasting damage, which can take years to repair. Earthquakes An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. At the Earth's surface, earthquakes manifest themselves by vibration, shaking, and sometimes displacement of the ground. Earthquakes are caused by slippage within geological faults. The underground point of origin of the earthquake is called the seismic focus. The point directly above the focus on the surface is called the epicenter. Earthquakes by themselves rarely kill people or wildlife. It is usually the secondary events that they trigger, such as building collapse, fires, tsunamis and volcanic eruptions, that cause death. Many of these can possibly be avoided by better construction, safety systems, early warning and planning. 1. what is a natural disaster ? 2. what are consequences of the natural disaster ? 3. what kind of natural disaster mentioned above happened with Nepal in 2015 ? 4. what is the reason of an earthquake ? 5. what is epicenter Giup mình với, mình đang vội.

mọi người giúp mình bài này nhé Part 3: Questions 76 – 85. Read the text and think of the word which best fits each gap. (2.0 points- 0.2/ each). Global Warming or Global Cooling Scientists have been constantly warning us that the earth is turning (76) ……………..………some kind of gigantic greenhouse and in the future there (77) ……………..………be a rise in temperatures everywhere. But other scientists disagree. They say that certain (78) ……………..………of the earth are not (79) ……………..………to get warmer but are going to (80) ……………..………cooler. Global cooling over parts of Europe will probably be greater (81) ……………..………global warming. The reason is simple: clouds. Warmer temperatures will (82) ……………..………more water evaporate and (83) ……………..………will lead to more clouds. These clouds will shade the earth from the sun, leading to cooler temperatures (84) ……………..………the day. Ecologists, however, insist that global warming will continue, in (85) ……………..………of increased cloudiness - and it is not going to be a good thing.
