Solution
Answer
The statement "The first minerals to crystallize from a magma are those with the lowest melting point" is False.
Explanation
In the process of crystallization from magma, minerals with the highest melting points are the first to crystallize as the temperature of the magma decreases. This phenomenon is described by Bowen's Reaction Series, which outlines the order in which different silicate minerals crystallize from cooling magma. According to this series, minerals such as olivine and pyroxene, which have high melting points, crystallize first when the temperature is still quite high. As the temperature drops, minerals with progressively lower melting points, such as amphibole, biotite, and finally quartz, crystallize.
In summary, the correct understanding is that as magma cools, minerals with higher melting points form first, contrary to the statement provided. Therefore, the answer is False.
