The difference between a text written in <u>procedural order</u> and a text written with a<u> cause-and-effect structure</u> is that the first one arranges information in the form of a sequence or process to achieve certain goal, while the second one exposes the relationship between conditions and its consequences.
A procedural text instructs the audience on how to complete a specific task. It provides a sequence of directions so that people can successfully perform an activity in a safe, efficient and appropriate way. Procedural writing can take several forms such as recipes, sciences experiments, directions for a map, manuals and procedural texts can take different forms such as brochures, posters or guidebooks.
A text structured as<em> cause and effect</em> explains the results of an action; in another way, it explains why something happened. Cause and effect is a common way to organize information in a persuasive writing mode.
Unlike procedural structured texts, cause and effect passages usually focus on explaining the reason why something occurs.
