After magma forms, it will typically rise towards the Earth's surface due to its lower density compared to surrounding rock. As it reaches the surface, it may erupt as lava through a volcano or form intrusive igneous rock formations beneath the surface.
Magma needs to cool and solidify to form a rock. This process can happen underground, resulting in intrusive rocks, or at the surface, leading to extrusive rocks. The rate of cooling and the mineral composition of the magma will determine the type of rock that forms.
In order to form magma, sedimentary, metamorphic, or igneous rocks must be exposed to high temperatures and pressures deep within the Earth's crust. This process causes the rocks to partially melt, forming molten rock called magma.
These are igneous rocks. They may form from lava at the Earth's surface, like basalt, or from magma beneath the ground, like granite.
igneous rocks
Minerals form from magma and lava through the process of crystallization. As the molten rock cools, atoms within the magma or lava arrange themselves into a crystalline structure to form solid mineral crystals. The specific minerals that form depend on factors such as the composition of the magma or lava and the cooling rate.

Gas must form in the vent of a valcano
Lava is simply magma that reaches the surface of the earth. If a magma flow never is emergent while it is still in liquid form, it cannot be termed lava. An example is a volcanic stock or a laccolith that remains beneath the surface entirely.

The lava would form pillow basalts.
As magma cools, elements combine to form minerals.
Volcanic activity will produce igneous rock.
Volcanoes form when magma from beneath the Earth's surface rises and erupts through a vent or opening in the crust. This can happen due to tectonic plate movements, hotspots in the mantle, or pressure buildup from magma chambers. The explosive release of gas, ash, and lava during an eruption is what we see as a volcanic event.

When felsic magma mixes with basic magma, it can lead to the formation of intermediate magma. This mixture can have a different composition in terms of silica and mineral content compared to the original magmas. The interaction can also trigger new chemical reactions, potentially changing the physical properties and eruption behavior of the magma.
