Magma is a geological source that consists of molten rock located beneath the Earth's surface. It is formed from the melting of rocks due to high temperatures and pressure in the Earth's mantle. When magma rises to the surface, it can erupt as lava during volcanic activity, contributing to the formation of new land and geological features. Magma also contains dissolved gases and minerals, making it a key source for understanding the Earth's composition and volcanic processes.
The location of a volcano can affect the magma composition by influencing the source of the magma. Magma composition can vary based on factors like the depth of the magma source, the presence of subducted materials, and the amount of water and gases present. Different locations can have different geological conditions that influence the composition of the magma erupted by a volcano.
The magma is primarily granitic/rhyolitic, but there are occasional basaltic lava flows.
In volcanic areas, groundwater heated by magma can be a source of hot springs, geothermal energy, and steam. This heated groundwater can also contribute to the formation of hydrothermal features such as geysers and fumaroles.
Magma chambers can provide geothermal energy, which involves converting the heat from molten rock within the chamber into usable energy, such as electricity or heat for buildings. This renewable energy source is considered sustainable and does not produce greenhouse gas emissions.
Magma can solidify and cool to form igneous rocks such as granite, basalt, or andesite, depending on the composition and cooling rate of the magma.

Magma is the semi-molten rock material on which the crust floats. The crust is the surface we live on.
Igneous.
When magma cools, it forms igneous rock.
The magma is primarily granitic/rhyolitic, but there are occasional basaltic lava flows.
