Which intrusive igneous form is a large granitic body, the cooled portion of a magma chamber, that solidifies deep inside the crust and appears on the surface only after the rocks above it are worn away?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Batholith
Batholiths are large granitic bodies formed when magma cools deep in the crust; they are the cooled portions of magma chambers and are exposed only after denudation removes the rocks above. Laccoliths are dome-shaped bodies with a level base, fed by a pipe-like conduit from below, while sills and dykes are thin sheets.
