What type of writing mainly describes a topic with factual information?

Expository discourse is specifically designed to inform or explain a topic by providing factual information. This type of writing is characterized by its focus on clarity and straightforwardness, presenting facts, explanations, and examples without the writer's personal opinions or emotions interfering. Expository writing is commonly found in textbooks, articles, and technical documents, where the primary goal is to deliver knowledge and enhance understanding.

This differs from other types of discourse. For instance, persuasive discourse aims to convince the audience of a particular viewpoint and often relies on emotional appeals and rhetoric rather than pure facts. Narrative discourse tells a story with a plot, characters, and a setting, often involving emotions and personal experiences. Descriptive discourse focuses on painting a vivid picture or evoking sensory experiences through detailed descriptions but does not prioritize factual information as its main goal. Thus, expository discourse is the best fit for the description of writing that centers around factual information.
