Igneous Rocks | National Geographic Society

Oct 10, 2019· 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.

Rocks & minerals | Minnesota DNR

Rocks are made of minerals. They can be made of a single mineral or a combination of several minerals. There are three main types of rocks: 1) Igneous (IG-nee-us) rocks are formed from hot, molten rock, called magma. Granite and basalt are examples of igneous rocks. 2) Sedimentary rocks are formed from bits and pieces of rock which have broken off.

Igneous rocks are formed by the melting of pre-existing rocks (igneous, metamorphic or sedimentary) into molten rock or magma. The subsequent cooling of magma forms new rock. The magma is either forced into older surrounding rocks (intrusive) or is discharged onto the Earth's surface by volcanic eruption (extrusive).
