What is the hole called when lava comes out of it?

Answer 1

Do you mean the hole it comes out of the ground through? That is a volcano.

More likely, you mean the hole made when the lava starts to cool and the liquid part inside can suddenly run out. That is a lava tube.

Answer 2

In the bottom of the volcano there is a pocket in which magma collects. This is called the MAGMA CHAMBER. The magma then moves through the a PIPE, a long tube that connects the MAGMA CHAMBER with the Earth's surface. There, the magma leaves the volcano through an opening called a VENT. The area covered by lava as it pours out of a VENT is called a LAVA FLOW. Lava may then collect in a CRATER, a bowl-shaped area around a volcano's central VENT.

Answer 3

The hole in the Earth's crust from which lava flows is called a volcanic vent or volcanic vent.

Answer 4
