The cause and effect diagram visually illustrates the relationship between two things when one thing makes something else happen. For example, if we eat too much food and do not exercise, we gain weight. Eating food without exercising is the "cause;" weight gain is the "effect." There may be multiple causes and multiple effects. In simpler words, a cause produces an event or condition; an effect is what results from an event or condition. The purpose of the cause-and-effect essay is to determine how various phenomena relate in terms of origins and results.
