4 · From early in the twentieth century, however, the trend has been to interpret the wide diversity of igneous rocks as being derived from only a few primary magmas. The process by which these magmas are modified is known as magmatic differentiation. For example, N. L. Bowen (1928), who championed this new interpretation, argued that

· Explanation: The general way minerals are formed is through the process of crystallization. There are many different example of this, including through the crystallization of magma or the crystallization of lava. The crystallization of magma cools inside the crust, while the crystallization of lava cools and then hardens on the surface.

Metamorphic rocks are a vital component of the Earth’s crust and play a significant role in geology. They are one of the three major rock types, alongside igneous and sedimentary rocks, and are formed through a geological process known as metamorphism.
