Question

It may be uplifted and then exposed by erosion.

It may form the core of a mountain range.

It is often a small part of a sill.

It is the largest intrusive igneous body.

Answer 1

The statement that is not true of a batholith is:

"It is often a small part of a sill."

A batholith is a large mass of intrusive igneous rock that solidified from magma deep in the Earth's crust, and it is typically much larger than a sill, which is a smaller, sheet-like intrusion of igneous rock that has spread between layers of sedimentary rock. Batholiths are generally not considered to be parts of sills, as they represent a different scale and form of igneous intrusion.
