Which term refers to materials that easily catch fire, such as wood?

The term that accurately identifies materials that easily catch fire, such as wood, is "combustible materials." These materials have the ability to ignite and burn when exposed to heat or flames. The key characteristic of combustible materials is their propensity to burn under normal conditions, which can pose fire hazards in homes, businesses, and other environments.

In contrast, noncombustible and incombustible materials refer to substances that do not ignite or burn easily, making them safer options in terms of fire risk. Flammable materials, while similar, typically refer to substances that ignite very easily and require less heat to catch fire compared to other combustible items. Therefore, while all flammable items can be classified as combustible, the broader category includes items that may catch fire but do not do so as readily as flammable substances. Thus, "combustible materials" is the most appropriate term for referring to items like wood.
