Which of the following is a classic example of an intrusive igneous landform that forms a dome-like shape by arching up the overlying sedimentary strata?

A. Laccolith✓ Correct Answer
B. Sill
C. Dyke
D. Batholith

💡 Solution & Explanation

A laccolith is an intrusive igneous formation characterized by a lens-like or dome-shaped body that forces overlying sedimentary strata to arch upward due to high magma pressure. Unlike sills that spread horizontally along bedding planes without significant arching, laccoliths display distinct localized bulging.
