Lava refers specifically to molten rock that flows on the surface of the Earth during a volcanic eruption. Molten rock, on the other hand, is the hot, liquid rock below the Earth's surface that has not yet erupted. Essentially, all lava is molten rock, but not all molten rock is lava.
When molten material from beneath the Earth's surface cools but doesn't harden, it forms a type of rock called volcanic glass, or obsidian. Obsidian is a black, glassy rock formed from rapidly cooled lava, which prevents the growth of mineral crystals typically found in other types of rock.
A natural hot melt composed of a solution of rock-forming materials, steam, and super-heated gases from which igneous rock results.
no. the mantle is only partially molten
No, lava and magma are not the same. Magma is molten rock beneath the Earth's surface, while lava is molten rock that flows out onto the Earth's surface during a volcanic eruption.
no! it can be in the mantle or the outer core
Below the surface, the molten rock is called magma; at the earth's surface it becomes lava, nothing has changed only the name of the liquid. Igneous rock is made by fire. Small wonder the magma from which igneous rock is formed can reach temperatures close to 1200 degrees Celsius.

This is false. Molten material below earth's surface is known as magma. It is only known as lava once it has been erupted onto the surface.
The liquid rock on the surface of Earth is called magma when it is beneath the surface and lava when it reaches the surface through volcanic eruptions. Magma is molten rock located beneath the Earth's surface, while lava is molten rock that flows out during volcanic activity.
Molten rock from underground that has risen to the surface. If it is only underground and has not went up, it is called magma.

No. Earth's mantle is made of rock which, contrary to popular belief, is not molten.
