Molten rock (magma) that spews from a volcano is called lava, When it cools, the lava forms igneous rocks.
The material that erupts from a volcano is called lava. It consists of molten rock that flows out during an eruption.
Lava is not a form of pyroclastic material. Pyroclastic materials are formed from volcanic eruptions and include ash, pumice, and volcanic rock fragments that are ejected into the air during explosive eruptions. In contrast, lava refers to molten rock that flows from a volcano, primarily during effusive eruptions.
Magma is inside the volcano, and it becomes lava when it comes out. :)
When a volcano erupts, molten rock reaches the surface as lava, ash, or similar material. This is addes to the surface of the volcano. So the mountain or edifice of a volcano is essentially a pile of material that has erupted in the past.
When spreading molten material rises from the mantle in the sea-floor and erupts, it can create sea mounts, which are underwater mountains. If enough material is ejected, the mounts will break through the surface of the water to create islands.
tephra
"Ejected debris" the the solid material shot into the air by an erupting volcano (as opposed to the gasses ejected by the same eruption).
These sorts of ejecta are sometimes called 'bombs'.
Ash Bombs Lava Magma etc.
Volcano
yes
The ash, rock and molten lava that's ejected during an eruption - falls back to earth and 'piles up' around the volcano, forming an island..
No. First of all, heat is not a substance. Something cannot be made of heat. Igneous rock forms from lava, magma, or tephra that has colled. Magma is molten rock in the earth's interior. Lava is molten rock that has been erupted onto the surface by a volcano. Tephra is material that has been ejected into the air by a volcano.

magma
The molten material that a volcano vents is called magma when it is still underground and lava when it reaches the surface. Magma is generated by the partial melting of rocks in the Earth's mantle, and its composition can vary depending on the type of volcano. When a volcano erupts, it releases lava, gases, and ash onto the Earth's surface.
