Let us dig deeper from the meaning of modeling:
Modeling is distinguished from other types of public performance, such as an acting, dancing or mime artistry, although the boundary is not well defined. Appearing in a movie or a play is generally not considered to be modeling, regardless of the nature of the role. However, model generally have to express emotion in their photographs, and many models have also described themselves as actors.
Types of Model, I'll give example on each type.
Fashion Model - are used mainly to promote apparel. Modeling generally can be divided into two categories (editorial and runway).
Glamour Model - Glamour photography emphasizes the model rather than products, fashion or environment. Typically the sexuality of the model is emphasized in glamour photography, while in fashion photography the emphasis is on the clothes.
Supermodel - Supermodels are highly paid, top fashion models. These (usually female) celebrities, also known as cover girls, appear on top fashion magazine covers, in catalogues and in fashion shows.
Fitness Model - Fitness modeling centers on displaying an athletic and healthy physique. Fitness models resemble bodybuilders, but with less emphasis on muscle size. Their body weight is usually similar to (or slightly heavier than) fashion models, but they have a lower body fat percentage due to increased muscle mass relative to fat mass.
