Magma is composed of many elements,consider magma of basaltic composition that is rich in Fe,mg,al,si,o, etc. as it rises from its region of formation say 200km deep into the earth,it will begin to risedue to density variations.It will reach a region at which P,T conditions are favourable for crystallization of a certain mineral say pyroxene.It will continue to rise but now it is molten but with pyroxene crystals.As it continues to rise mdifferent minerals will crystalise such as amphibole,biotite etc.Now notice that these minerals are crystallising at the same time and there crystals are growing together thus crystals will intergrow forming an igneous rock.If it consolidates deep in the earth it becomes an intrusive rock say Gabbro or if it is extrusive it can be a Basalt.The same apllies to all igneous rocks except that rocks depend on the composition of the from which they originate
Extrusive igneous rock is formed from the crystallization of minerals as the lava cools.
Yes, during the cooling of molten rocks, different elements join together to form minerals through crystallization. The specific minerals that form depend on the composition of the molten rock and the cooling rate. This process is responsible for the diversity of minerals found in igneous rocks.
Most igneous rocks are made up of silicate minerals, such as quartz, feldspar, mica, amphibole, and pyroxene. These minerals are rich in silicon and oxygen and form the bulk of the composition of igneous rocks.
yes because it is made of all different minerals

It doesn't necessarily matter what the minerals are, as long as they form from cooling magma or lava. Igneous rocks are formed by the solidification of cooled magma (molten rock). They may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
Rock
Obsidian is an igneous rock that technically is not composed of minerals. It is a natural glass.
Extrusive igneous rock is formed from the crystallization of minerals as the lava cools.
When minerals melt, they can form an igneous rock called granite. Granite is typically composed of quartz, feldspar, and mica minerals that solidify from a molten state, either deep underground or at the Earth's surface.

Minerals form in igneous rock as magma or lava cools. The minerals will form from the available chemicals in the magma as their crystallization temperature is reached. The sequence of mineral crystal formation from magma is described in the Bowen's Reaction Series. Metamorphic rock minerals are aligned, altered, or recrystallized from existing rock minerals due to the effects of heat and/or pressure.

Yes, igneous rocks can often be identified by their minerals because the minerals present in an igneous rock are usually specific to the conditions under which the rock formed. By studying the mineral composition of an igneous rock, geologists can determine factors such as the rock's cooling rate, temperature, and pressure during formation.
