Description of the main parts of a volcano: the magma chamber, where, under great pressure, lava and magmatic materials bubble up at temperatures of more than 1.000 ° C; the fireplace, which connects the magmatic chamber to the outside; the crater, the mouth of the volcano, through which the volcano expels magmatic materials, and the cone, the mountain that is formed with the materials expelled by the crater and which covers the chimney.
