text: In conclusion, the "face" on Mars is just a natural landform, not something that was created by aliens. In the future, we might find out for certain what that "face" is. We aren't one hundred percent positive it is a mesa, but we know it wasn't aliens. I will be thrilled to find out what it is soon, and I think you will be, too.The Facial Ation Coding System(FACS) is seeming to be useful in a classroom because it can detect when someone may be confused on a certain subject. As well as the FACS can detect if there are emotional issues that are imparing the student to learn.
