n.

magma
(māg’mə)
Plural magmata (māg-mä’tə) or magmas
The molten rock material that originates under the Earth’s crust and forms igneous rock when it has cooled. When magma cools and solidifies beneath the Earth’s surface, it forms what are known as intrusive rocks. When it reaches the Earth’s surface, it flows out as lava and forms extrusive (or volcanic) rocks.

Molten rock usually located deep within the mantle of the Earth that occasionally comes to the surface through cracks in the mantle or through the eruption of volcanoes.

Note: When magma cools and solidifies, it forms igneous rock, of which lava is one type.
