The amount of fluorine in the fossil decreases with the age of the remain.

Question

BlackTom AI · Accepted Answer

The statement in question is about how fluorine content in a fossil changes with the age of the remain.
Option 1: True. This would assert that fluorine decreases as the fossil gets older. In reality, fluorine dating shows that fluorine accumulates in bone over time from groundwater; therefore, older fossils tend to have higher fluorine concentrations. So claiming a decrease with age contradicts the established principle of fluorine dating.
Option 2: False. This aligns with the actual mechanism of fluorine uptake, where bone absorbs fluorine from the surrounding groundwater over geological time. The longer the time, the more fluorine can diffuse into the fossil, leading to greater fluorine content in older specimens. Consequently, the proposition that fluorine decreases with age is incorrect, making this the correct choice for the true/false statement.
In summary, the idea of decreasing fluorine with age misses the key concept of fluorine accumulation over time, which is central to fluorine dating techniques. The observable trend is the opposite of what the statement claims, hence the statement is false.
