Plutonic rocks, generally coarse grained, interlocking texture, high density. eg. Granite
There is no ladder if (of?) rocks under the earths surface, your question is meaningless.
At depths of 50 to 200 km below Earth's surface rocks will melt.
Course grained texture.
extrusive- when melted rock material coools on earths surface instursive-when the melt cools below earths surface
eroison
These are called veins
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.
Igneous rocks that form below the Earth's surface are called intrusive igneous rocks (or plutonic).
