rocks that formed at very high temperatures from siliceous (silica rich) melts.
Igneous rocks are formed by the crystallization of minerals within cooling magma
e.g. basalts and granites. Produced from hot magma rising up from the lower crust or upper mantle, which then cools and solidifies.
formed by solidification from a molten state (magma), or cooled at great depths (plutonic rocks), or blown into the air as rock fragments (volcanic rocks).
Rocks formed by the solidification of molten material from far below the earth's surface.
Rocks formed by the solidification of molten material from far below the earth's surface.
Rocks formed by the solidification of molten material from far below the Earths surface.
Igneous rocks are one of the three major rock types and are basically rocks that solidified from magma. Magma is the term for liquid or melted rock and is usually quite hot.
