Considerable depth = At great depth.

So, Plutonic is the right one.

High depth - plutonic rock/granite "gabroo.

Shallow depth - Hypabyssal, eg dolerite.

Surface - volcanic. eg basalt.

Plutonic rock is also a part of igneous rock. Then, why the igneous rock is not a considerable answer.

Plutonic rocks are formed by the cooling of magma at considerable depths from the earth's surface. These rocks are also known as intrusive rocks because they intrude into the existing rock formations. Plutonic rocks are different from volcanic rocks, which are formed due to the cooling of lava on the earth's surface.

The rocks made from the cooling and solidifying of molten rock (magma) are called igneous rocks and the two categories of igneous rocks - are volcanic and plutonic rocks.

Volcanic rocks are found on the earth's surface whereas plutonic rocks are found at a considerable depth from the earth's surface.

Plutonic rocks are coarse-grained crystalline igneous rocks formed by consolidation of molten rock material or magma below the Earth's surface (Latin Pluto, god of the Underworld).

Intrusive=plutonic.

Plutonic rock.

Because of larger depth.

What about Igneous rocks?

Naveed Kamal Marwat said:   5 years ago
Plutonic -> Considerable depth.
Hypabassal -> shallow.
Volcanic -> Surface.
