Below the crust of the earth, the top layer of the mantle is a hot liquid rock called magma. The crust of the earth floats on this liquid magma mantle. When magma breaks through the surface of the earth in a volcano, it is called lava.For every 100 meters you go below ground, the temperature of the rock increases about 3 degrees Celsius. Or for every 328 feet below ground, the temperature increases 5.4 degrees Fahrenheit.hen magma breaks through the surface of the earth in a volcano, it is called lava.

Similarly, liquid magma also turns into a solid &#8212 a rock &#8212 when it is cooled. Any rock that forms from the cooling of magma is an igneous rock. Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind.When magma rises from deep within the earth and explodes out of a volcano, it is called lava, and it cools quickly on the surface.Rock formed in this way is called extrusive igneous rock.agma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind.
