What scale can we use to help evaluate an object's timeline and history?
For geologists, paleontologists, archaeologists, and anthropologists, objects of study are often talked about in terms of thousands, millions, or even billions and positioned within the geological timescale of Earth.
We understand centuries based on family trees and history books, and we have a conceptual sense of a few thousand years.
The DGB sites are constructed in a system of terraces and platforms built using a dry stone architecture that doesn't appear in any other sites using local granite and rocks, with stairs and silos being placed throughout.
After studying various sections of whole and collapsed walls, archaeologists discovered that the walls were not constructed with shaped square stones, but rather built using stones naturally lying around and carefully fitted together with smaller stones propping up and holding together the walls.
The Diy-Gid-Biy sites are of varying sizes, with DGB-1 and 2 being the largest.
They are spread out over approximately 25 km, although DGB-1 and 2 are only 100 meters apart and are sometimes referred to as the same site.
Through the use of radiocarbon dating, archaeologists have been able to determine that the majority of the 16 sites were first constructed in the 15th century, although the wide range of dates from the various stages of development had originally made it difficult to figure out the structures beginnings.
DGB-1 is a unique anomaly though in that radiocarbon dating places that particular site's origins back farther to around 1250 AD.
With dice at the ready, students can roll their way to better understanding of how an isotope decays.
When it comes to talking about time and age on a geologic scale, our everyday watches, clocks, and units of measurement fall short. We can count seconds and even measure smaller units that help us evaluate the outcome of a race.
Since protons and neutrons weigh about the same, the atomic mass of ordinary carbon is 6 6 = 12.
