Exercise 5.19: Revise for unity
Read the paragraphs. Cross out sentences that are not connected to the topic sentence.
- The aftermath of an earthquake is more dangerous than the earthquake itself. When an earthquake occurs, the shaking causes problems with existing buildings and construction (United States Geologic Survey, n.d.). For example, gas lines may break because the ground around them shifts, and broken gas lines are extremely dangerous to people. Gas lines smell terrible when they are broken. Other dangers after an earthquake include landslides and tsunamis. The sudden energy of the earthquake sends either land or water moving, and anything in the path can be destroyed (USGS, n.d.). Earthquakes can have more energy than hurricanes. Tidal waves from tsunamis can swallow entire countries in the Pacific. When compared to the dangers directly associated with the earthquake, we can see that the aftermath is also important to be prepared for.
- One cause of pollution is huge factories. In the factories we produce thousands and thousands of different things for humanity. The biggest factories are in the food, petroleum, forest, auto, and pharmacy industries. Factories burn coal, petroleum, and wood. Having many factories would not be a problem if they used different energy. The problem is that no matter what kind of combustible material we are talking about, all of them pollute our air. They also are difficult forms of energy to replace so we will have less fuel in the future. Pollution has been a part of earth even millions of years ago but not the amount of contamination that we now observe. The Earth's ozone layer has started to thin because of the monumental measure of harmful substances in the air. The factories emit into the air harmful chemicals, and every single one of these substances is poisoning the air. Huge factories are in some ways useful for humans but also harmful to the environment and pollute the air.
