Answer 1

When molten rock flows or erupts through a crack on the earth's surface, it came from a Volcano.

What is a Volcano?

A volcano is a channel in Earth's crust through which molten rock flows. Volcanoes can develop from the subduction of a plate under another plate below the earth crust. At the boundaries where plates exist, molten magma  rises in cracks between the two plates, leading to the formation of volcanoes.

  Below the earth surface, molten rock is referred to as magma but as soon as it erupts above the earth's surface, it is referred to as Lava.

Therefor, according to the question, when molten rock flows or erupts through a crack on the earth's surface, it came from a volcano.
