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.
Its melting, then re-solidification.
Extrusive igneous rock
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.
Igneous rock is formed from the solidification of magma as it cools.
