Radiocarbon dating is not used for dinosaur bones because dinosaurs lived millions of years ago, and radiocarbon dating is only effective for dating objects up to around 50,000 years old. Dinosaurs are too old for this method to accurately determine their age.

What reduces friction in a joint?

Lubricating fluids like synovial fluid in the joint help reduce friction by providing a smooth surface for bones to glide against each other. Additionally, the cartilage covering the ends of bones acts as a cushion, reducing friction during movement. Strengthening the muscles around the joint can also help stabilize and support it, reducing friction.


How does ultraviolet waves help your teeth and bones?

Ultraviolet waves help your body produce vitamin D, which is essential for the absorption of calcium and the maintenance of healthy teeth and bones. UV exposure triggers a chemical reaction in the skin that leads to the formation of vitamin D, which helps regulate calcium and phosphorus levels in the body, supporting bone health. However, it's important to balance UV exposure to avoid skin damage and potential health risks.

Why can carbon-14 be used to date a 40000 year old tree but U-Pb cannot?

C14 is continuously made in the atmosphere by the effects of solar radiation on Nitrogen14. There is an equilibrium up there between how quickly C14 is made and how quickly it decays to C12 because the gases circulate. Obviously this circulation stops when a C14 molecule gets incorporated into a plant or something that ate the plant. Over time the C14 in a tree disappears while C14 in the iar keeps gettin renewed. Our dating technique relies on the difference between how much C14 is left in the tree compared to what can be found in the air. I dont think the same can be said of U. It and other heavy elements are not airborne and were in any case made in a dying sun. Therefore the ratio of Pu, U, Pb and other heavy elements is the same whether in a tree or in the soil that the tree grew up in. So while any U that found its way into the tree will have decayed, the U in the soil will have decayed too. Therefore our C14 (which relies on measuring differences) cannot be used. Full disclosure: I have MSc Molecular Biology but I am NOT an expert in carbon dating. Double check before you rely on this information as gospel.
