Oct 19, 2023 · 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.. Igneous rocks can have many different compositions, depending on the magma they cool from.
Lava. Igneous rocks, intriguing formations originating from lava, are the solidified result of volcanic eruptions. During these eruptions, volcanoes expel hot, molten rock known as magma or lava. As this lava reaches the surface and cools, it hardens into what we know as igneous rocks.

View FREE Resources. What are Igneous Rocks? Igneous rocks are one of the three main types of rock, each of which is formed in a different way. Igneous rocks are formed by magma, or lava, as it cools down and solidifies. In order to understand how this process works, we need to understand what our planet is like below the thin crust on the surface.
