Archaeology
A tell is a hill created by many generations of people living and rebuilding on the same spot. Over time, the level rises, forming a mound. The single biggest contributor to the mass of a tell are mud bricks, which disintegrate rapidly. Excavating a tell reveals buried structures such as government or military buildings, religious shrines and homes, located at different depths depending on their date of use. They often overlap, horizontally, vertically, or both. Archaeologists excavate tell sites to interpret architecture, purpose, and date of occupation. Since excavating a tell is a destructive process, physicists and geophysicists have developed non-destructive methods of mapping tell sites.
