The liquid form evolved from earths crust which is released during volcano occurs.

The rocks made from the cooling and solidifying of molten rock (magma) are called igneous rocks and the two categories of igneous rocks - volcanic and plutonic rocks. Volcanic rocks found on earth surface whereas plutonic rocks found at considerable depth from earth's surface.

Sir, Igneous rocks and Volcanic rocks are same. Then why the answer is Plutonic rock.

Sandy said:   9 years ago
Plutonic is the type of igneous rock formed under the surface.

Why not Volcanic rocks?

Igneous rocks are formed due to cooling and solidification of magma.

Igneous rocks have two types-.

1) Volcanic rocks which are formed on the earth surface.

2) Plutonic rocks which are formed at a considerable depth below the earth surface.

So I think plutonic is the very accurate answer.

Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.

Plutonic rock is the correct answer.

What about pegmatite? Give details about it.
