Here's why:
* Magma vs. Lava: Magma is molten rock found beneath the Earth's surface, while lava is molten rock that has erupted onto the surface.
* Neck of a Volcano: The neck of a volcano is the conduit that connects the magma chamber to the surface.
* Magma Chamber: The magma chamber is a large underground reservoir of molten rock that feeds the volcano. It's located deep within the Earth's crust, typically several kilometers below the surface.
Therefore, the magma chamber is the main source of lava for the volcano, and it is located in the neck of the volcano.
