Igneous Rocks: Formation, Types and Examples | Earth Eclipse

 · The terminology Igneous means fire or heat. In this sense, igneous rocks are formed when molten rock (magma) solidifies either underneath the earth''s crust to form plutonic (intrusive) igneous rocks or on the surface of the earth to form volcanic (extrusive) igneous rocks.

Igneous rock

Igneous rock is formed when magma, which is liquid molten rock, cools or sets, solidifying into rock and rock formations. Extrusive rocks are rocks that have formed on the surface of the earth. This occurs when magma bursts forth from the mantle or crust on to the surface.

Igneous rocks form as molten material cools and crystallizes into rock. As the molten material cools, chemical compounds in the melt crystallize into minerals at different temperatures Magmatic differentiation involves processes by which chemically different igneous rocks, such as basalt and granite, can form from the same initial magma High-temperature minerals can crystallize and settle …

How do igneous rocks form? (Chapter 8)

Igneous rocks are those formed by the solidification of molten rock. This molten material, which we call magma, is formed at depth in the Earth and rises toward the surface, where it cools and solidifies, either beneath the surface, where it usually has time to crystallize, or on the surface as volcanic rocks, where cooling may be rapid enough to form glass.

Igneous Minerals | National Museum Wales

Igneous minerals form during the cooling and solidification of molten rock, or magma, produced at high temperatures (around 650 to 1200 C) beneath the Earth''s surface.
