Intrusive igneous rocks.
Intrusive rocks are light.
Rocks can be classified as either igneous or intrusive, but not both. Igneous rocks are formed from the cooling and solidification of magma (molten rock) above or below the Earth's surface. Intrusive rocks specifically form from magma that cools and solidifies underground, beneath the Earth's surface.
Intrusive igneous rocks.
Yes. More exactly, intrusive igneous rocks.
Igneous rocks that form below the Earth's surface are called intrusive igneous rocks. Examples include granite, diorite, and gabbro. These rocks cool and solidify slowly, allowing large crystals to form.
Some do. These are called extrusive igneous rocks. However a large portion of igneous rocks form beneath the surface. These are intrusive igneous rocks.
"intrusive" means forced into something, "extrusive" means forced out onto the surface. The igneous magma reaching the surface is therefore extrusive , producing extrusive igneous rocks, and all the rest of the magma is intrusive, producing intrusive igneous rocks.
