Question

Quizplus · Accepted Answer

A laccolith is a type of igneous intrusion that forms when magma is injected into sedimentary rock layers and spreads horizontally, causing the overlying rocks to bulge upward and form a dome-shaped structure. Sills are similar intrusions but they are mostly parallel to the bedding planes of the host rock and don't bulge as much. Dikes are vertical intrusions that cut across the host rock. Batholiths are much larger intrusions that cover an area of at least 100 square kilometers.
