Okay I have a question. How can they say "This bone is 8 million years old" Without knowing for sure. How do they figure out how old something is I guess is what i'm trying to say.

Accepted Answer

∻Answer∻ ⚹ Scientists determine the age of bones and fossils through various dating methods, such as radiometric dating, which measures the decay of radioactive isotopes within the materials. ⚹ ∻Key Concept∻ ⚹Radiometric Dating⚹ ∻Explanation∻ ⚹Radiometric dating, particularly carbon dating for more recent fossils and potassium-argon or uranium-lead dating for older materials, allows scientists to estimate the age of an object by measuring the decay of isotopes over time. The rate of decay is known and constant, which provides a "clock" that starts ticking when the organism dies. By measuring how much of the radioactive isotope remains, scientists can calculate how long it has been since the organism's death. For very old fossils, like those that are millions of years old, methods like potassium-argon dating are used because they can measure much longer time periods.⚹◊What methods and techniques do archaeologists and paleontologists use to determine the age of bones and fossils in AP World History?⍭ Generate me a similar question◊
