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.

∻Answer∻ ⚹ Scientists determine the age of bones and fossils using dating methods such as radiometric dating, which measures the decay of radioactive isotopes within the materials. ⚹ ∻Key Concept∻ ⚹Radiometric Dating⚹ ∻Explanation∻ ⚹Radiometric dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they formed. For example, carbon dating uses the decay of carbon-14 to estimate the age of organic materials, while other methods like potassium-argon dating are used for older geological samples. The decay occurs at a predictable rate, known as the half-life of the isotope, allowing scientists to calculate the time elapsed since the material was formed.◊What methods did scientists use to determine the age of ancient bones in prehistoric times without the use of modern technology?⍭ Generate me a similar question◊⚹
