molten material in the form of lava that undergoes the process of crytallization on the natural terretial surface​

Sagot :

The answer is “Igneous rocks”. Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.
