The process of minerals formation from magma is called crystallization. During this process, minerals solidify and form crystals as the magma cools and hardens.
crystallization above ground and crystallization below ground
Igneous rocks like rhyolite or andesite are formed when magma undergoes crystallization above ground. These rocks cool relatively quickly, resulting in smaller mineral crystals compared to rocks formed from magma crystallizing deep underground.
Crystallization and cooling magma are related in the sense that cooling and crystallization occurs simultaneously. As the magma cools it crystallizes, the faster the rate of cooling the quicker crystals would develop and the slower the cooling the larger the crystals in other cases when the magma cool so rapidly crystal development may not be so prominent.
Yes; through the process know as fractional crystallization, which changes the composition of the magma, therefore changing the minerals that eventually crystallize from it. Fractional crystallization occurs largely from the varying temperatures at which minerals crystallize.

As a magma crystallizes it undergoes fractional crystallization in which mafic minerals crystallize first and felsic minerals crystallize last. Therefore, as fractional crystallization occurs the magma becomes increasingly less mafic and increasingly more felsic. The viscosity also increases as a magma becomes more felsic.
The magma starts cooling and crystallizing. The crystallization cause the magma to change composition. This is referred to as magma evolution.
Crystallization of minerals from magma occurs as it cools and solidifies. As the temperature decreases, different minerals crystallize at varying temperatures due to their distinct melting points, a process known as fractional crystallization. This results in the formation of various minerals, with early-formed crystals often settling to the bottom of the magma chamber, leading to a diverse range of rock types. Ultimately, the cooling rate and composition of the magma significantly influence the crystallization process and the resulting mineral assemblage.
