A cause and effect essay includes some elements of essay writing that might be considered more professional than those a descriptive or narrative essay might include. It is very important, for instance, that your tone be reasonable, and that your presentation be factual and believable. Sources are often required in a cause & effect essay, and your choice of these sources is important as they reflect on the validity of your paper. Additionally, the first-person point of view does not work as well in professional cause and effect essays.
