Conclusion analysis

Good conclusions usually refer back to the question or title and address it directly - for example by using key words from the title.
How well do you think these conclusions address the title or question? Answering these questions should help you find out.

  1. Do they use key words from the title or question?
  2. Do they answer the question directly?
  3. Can you work out the question or title just by reading the conclusion?
  • Volcanoes are more dangerous hazards than earthquakes - Discuss the truth of this statement.

    "In conclusion I believe that the statement 'volcanoes are more dangerous hazards than earthquakes' to generally be false. Although earthquakes can be prepared for a lot better than volcano eruptions, earthquakes are less easy to predict and cause a substantial amount more damage. Earthquakes are also more frequent and usually affect a larger area and can also cause tsunamis, floods, fires, landslides and the liquefaction of soil. Iden Ranapour 1"

  • The extent to which earthquakes are hazardous depends on where and when they are experienced

    "To conclude, the key spatial and temporal factors listed above leads me to believe that the extent to which earthquakes represent hazards DOES depend on where and when they are experienced. In particular, 'where' factors such as level of development and rural-urban disparities as well as 'when' factors such as time of day and time between hazards are crucial in determining the extent of damage caused by an earthquake. However every earthquake is different and it is only when a combination of the above elements come together does an earthquake become a real hazard. After all, it is estimated that over 1,400,000 earthquakes occur annually with only up to 100 of those deemed to be potentially hazardous."

  • Volcanoes are more dangerous hazards than earthquakes discuss the truth of this statement.

    "Both hazards are deadly and ruin both property and human life; however volcanoes in my opinion are more dangerous than earthquakes. Earthquakes although cannot be predicted can be protected against saving thousands of lives. Volcanoes although can be predicted cannot be defended against, even if towns are evacuated they are still destroyed creating huge humanitarian and economic problems. Accurate volcano prediction if in place isn't always linked up with towns in danger; this makes the prediction useless anyway. Finally Volcanoes also have lasting implications; their secondary effects such as lahars can be felt for generations."
