Final answer:
The sequence of mineral crystallization in a cooling igneous melt is indeed called Bowen's Reaction Series, and the statement is true. Minerals like feldspar crystallize early at high temperatures, whereas minerals like quartz crystallize later at lower temperatures.
Step-by-step explanation:
The statement that the sequence in which minerals crystallize in a cooling igneous melt is called Bowen's Reaction Series is True. As a molten igneous rock cools, different minerals crystallize at different temperatures. For example, feldspar tends to crystallize at high temperatures early in the cooling process, often resulting in well-formed crystals with straight sides. Other minerals like quartz crystallize at lower temperatures and fill the spaces between earlier-formed minerals.
Intrusive igneous rocks, which cool below the Earth's surface and cool gradually, have large mineral grains due to the slow cooling rates. This allows individual crystals to grow large. On the other hand, extrusive igneous rocks that cool quickly on the Earth's surface have fine grains or a lack of crystal growth because they did not have time to develop large crystals.
