igneous rock
Solidification can occur when molten rock cools, or when sediments undergo lithification.
A type of rock group that forms from the solidification of magma is indigenous rocks. One example of this is sulphur.
That would be the igneous rock.
Rhyolite
A product of the solidification of magma or molten lava is igneous rock.
Uplift and solidification
Yes, sedimentary rock can undergo metamorphism due to heat and pressure, transforming it into metamorphic rock. If the metamorphic rock experiences further heat and melting, it can become igneous rock through processes like melting and solidification.
Extrusive igneous rock
Its melting, then re-solidification.
Magma, or molten rock, must undergo solidification in order to form igneous rocks. This process involves cooling and hardening of the molten rock to become solid.
The process always required before igneous rock forms is the cooling and solidification of magma or lava.
The first rock on Earth was formed from the cooling and solidification of magma on the surface.
