Molten rock collects in a magma chamber beneath the volcano.
A volcano happens whenever the pressure of the melted rocks below the earth becomes great enough to break through the surface.
volcano
The melted rock coming from a volcano is called lava.
A volcano does not make magma. The magma is created underground by melted rocks due to the earth's core temperature. When na big amount of magma is created, the volcano feels pressure, and then it errupts magma, but it does not make it.
Igneous rocks.
There are two main types of igneous rocks: intrusive (plutonic) rocks form beneath the Earth's surface from cooling magma, such as granite and diorite; extrusive (volcanic) rocks form from lava cooling on the Earth's surface, such as basalt and rhyolite.

igneous rocks- rocks that are formed from melted minerals. ore-a rock that has a large amount of minerals.
lava
Rocks that can be melted include igneous rocks like granite and basalt, which have high melting points. These rocks can be melted through processes like volcanic activity or in a laboratory setting to form magma or lava. Metamorphic rocks, like marble and quartzite, can also be melted under extreme heat and pressure.
Magma is the substance inside volcanoes. If the melted igneous rocks are inside a volcano, it is called magma. When the substance exits the volcano, it is called lava. When you see fire, that is when a lava flow travels down a mountain and reacts with other mediums such as houses.
