Magma is liquefied rock, viscous rather than "plastic" (as in the rheid of the hot mantle). Magma can form within the lithosphere, in locations such as subduction zones, continental rift zones, mid-ocean ridges, and hotspots above the mantle.
* The pressure in the mantle is too high for rock to become liquid. In the outer core, the heat becomes high enough to form liquid, but this dense liquid can never reach the surface of the Earth.

Igneous rock is formed from the crystallization of molten magma or lava. Intrusive igneous rock is formed beneath Earth's crust from magma. Extrusive igneous rock is formed above Earth's crust from the crystallization of lava.
the crust is made up of solid rock and mantle is made up of molten rocks
The molten material that reaches earth's surface is lava :)
Magma is molten material that when cooled forms a solid called igneous rock

It starts with molten material [magma], when volcanic activity starts the molten material turns into igneous rock.
The molten material then spreads out, pushing the older rock to both sides of the ridge. As the molten material cools, it forms a strip of solid rock in the center of the ridge. Then more molten material flows into the crack. The material splits apart the strip of solid rock that formed before, pushing it aside.

Magma is the semi-molten rock material on which the crust floats. The crust is the surface we live on.
Molten material below the surface of the Earth is called magma. It consists of molten rock, gases, and suspended solids. Magma can eventually erupt onto the Earth's surface as lava through volcanic activity.
