What type of rock results from the solidification of a molten substance coming from inside the Earth?

Intrusive

The rocks we call intrusive form in darkness, out of sight, beneath the Earth's surface. They originate from the slow cooling of initially fiery material from the Earth's mantle, making its way through cracks and faults. This slow crystallization process allows for the development of impressively sized minerals, offering a fascinating spectacle once revealed in the light of day. These witnesses to our planet's hidden activity not only reveal the power of geological forces but also the beauty that can emerge from invisible and underground processes. Their study provides crucial clues about the composition of the Earth's mantle and the dynamic processes that have shaped our world for billions of years.
