Grains found in igneous rock are minerals that solidified from a molten state. They can be coarse or fine, depending on the cooling rate of the magma. Common minerals found as grains in igneous rock include quartz, feldspar, mica, and olivine. The size, shape, and arrangement of these grains can provide clues about the cooling history and composition of the rock.
Granite is an intrusive igneous rock (formed from the slow cooling of magma underground), the major component of the continental crust, coarse grained, and composed of quartz along with a variety of feldspar minerals and micas.
The molten lava solidifies into solid rock on cooling.
Granite is an igneous rock, which means it is formed from cooling and solidification of molten magma deep within the Earth's crust. It is composed mainly of quartz, feldspar, and mica minerals.
No, igneous rocks are not made up of only one mineral. They are typically composed of a variety of minerals, which are formed by the cooling and solidification of molten rock material. Some common minerals found in igneous rocks include quartz, feldspar, and mica.

Yes. When magma cools and solidifies, mineral crystals are formed.
Several minerals form in slow cooling magma. Some of those minerals are quartz, plagioclase feldspar, and potassium feldspar. These are the same minerals that are found in granite.

In Bowen's reaction series, feldspar minerals go through a continuous change of composition, while iron-magnesium groups have an abrupt change of mineral types. When magma cools, the feldspars that form are calcium-rich. As cooling continues, the feldspars react with magma and the feldspar composition changes. The result is a zoned crystal with sodium-rich outer layers and calcium-rich core. For iron-magnesium minerals, when magma starts cooling, a mineral begins to crystallize. However, when the magma temperature drops, a whole new mineral begins to form. The previously formed minerals reacts with the magma and is converted into the new mineral.
When molten iron cools and solidifies, this is called "fusion".
