An expository written piece structured in descriptive structure goes into great detail describing a topic. A main idea is presented and characteristics, examples, and features are provided, to help the reader fully understand the topic being discussed.
When using a sequence or list structure in expository writing, information and ideas being given are presented in chronological order. A series of steps, or a hierarchy of events is provided. Specific cue words are used, when writing in this style. They include; first, second, third, next, then, furthermore, the following, and finally.
The compare and contrast approach to expository writing involves discussing the similarities and differences between people, places, items, or events. In order to write in compare and contrast structure, an author must be able to identify ways in which at least two or more things are the same and the ways they are different, without bias and in an informational tone.
The cause and effect sequence is present when an author effectively shows how one event leads to another. It is not necessary for only one cause or outcome or result to be present in this style. As long as facts are provided, an author can show how many events can be the result of a single cause, or how a single event can be caused by a number of different factors.
When using a problem and solution format for expository writing, a clear problem must be defined. After it is clear what the dilemma is, the author then gives a number of optional solutions that could potentially solve the problem. Works written in this style should end by clearly stating the best possible solution, while providing an explanation about why that particular solution is better than other options.
