It's the molten rock that comes out of volcanoes when they erupt and that streams downhill while it's still so hot that it is liquid.
A planet is most likely to have tectonic activity if it has a molten interior, composed of materials that can flow and deform. Tectonic activity is driven by the movement of these materials in the planet's interior, causing the crust to shift and create features like mountains, earthquakes, and volcanoes.
volcanoes are mounds of earth that sometimes spurt molten rock out
