Nov 15, 2018 Igneous Rocks Definition. Igneous rocks are created when a melt cools and freezes solid. High temperatures inside the earth cause a solid rock to transform into a flowing melt. When this melt cools, it forms a new igneous rock. The word igneous is. Igneous definition is - formed by solidification of magma. How to use igneous in a sentence. Formed by solidification of magma; relating to, resulting from, or suggestive of the intrusion or extrusion of magma or volcanic activity.
Igneous rocks are formed when molten rock (magma) cools and solidifies, with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
