The volcano poured molten rock.

Tom is a solid and determined man, but sometimes he's as impetuous as a river of molten lava.

Earth has a core of molten iron-nickel.

The rapid spin of the Earth along with the molten metallic core produces the Earth's magnetic field.

She poured the molten lead into a funnel.

Earth’s magnetosphere is created by the constantly moving molten metal inside Earth.

Jupiter does not have a molten metal core; instead, its magnetic field is created by a core of compressed liquid metallic hydrogen.

An explosion caused by lava oozing into the ocean sent molten rock crashing through the roof of a sightseeing boat off Hawaii's Big Island, injuring 23 people.

It was a spacious harbour, sheltered deep / from access of the winds, but looming vast / with awful ravage, AEtna's neighbouring steep / thundered aloud, and, dark with clouds, upcast / smoke and red cinders in a whirlwind's blast. / Live balls of flame, with showers of sparks, upflew / and licked the stars, and in combustion massed, / torn rocks, her ragged entrails, molten new, / the rumbling mount belched forth from out the boiling stew.

Earth’s magnetic field is generated from its outer core, 1,800 miles below the surface, comprised of molten iron and other metals that are constantly churning and acting like a giant generator – known as geodynamo — that generates electric currents that produce the magnetic field.
