What scientific methods are used in archaeology?

Archeology uses methods from many scientific branches and many fields of study, such as sociology, anthropology, forensics, history, geology, and natural science. For example, sociology helps to map the social constructs within an ancient society. Forensics and anthropology can help to date bones, identify the sex of a skeleton, and identify the cause of death especially if death was due to trauma. Geology is important to identify age of a site using deposits of soil.
