In this kind of essay, the aim is to explain the causes (reasons) or the effects (results) of an event or situation. e.g. Causes of air pollution (multiple factors leading to air pollution). e.g. Effects of watching too much TV (many effects of a situation).
Sometimes an event causes something to happen, and that situation leads to another event, and it causes another event to happen. This is called the causal chain or domino effect. e.g. Use of deodorants will bring the end of the world.
There may be several causes or effects of a situation. However, in a student essay, it is advisable to keep the number of major points to 2 or 3, which form separate developmental paragraphs.
Depending on the topic, there may be three patterns of organization: 1. Multiple causes-->effect
In this pattern, the organization is as follows:
thesis statement: Air pollution is caused by the following factors: exhaust gases from cars, uncontrolled factory releases, and burning of low-quality coal for heating. I. exhaust gases from cars
A. government does not have enough control
B. citizens are not conscientious
II. uncontrolled factory gases
A. no regular checks on gases released
B. factories are inside the borders of residential areas III. burning of low-quality coal for heating
A. no governmental control
B. other forms of energy too expensive
Each developmental paragraph is devoted to one of the causes of air pollution. Each cause is supported by two minor supports. While writing, these major and minor ideas should be adequately explained and exemplified as well.
2. Cause-->Multiple effects
In this pattern, the effects of a certain situation are explained in separate paragraphs, with the following organization:
