Question

Quizplus · Accepted Answer

A sill is a nearly horizontal intrusion of magma that forms between sedimentary layers. It is concordant, meaning it follows the layering of the sedimentary rock, and tabular, meaning it has a flat top and bottom. A dike is a vertical or nearly vertical intrusion of magma that cuts across sedimentary layers. A batholith is a large, irregularly shaped pluton that forms deep in the Earth's crust. A laccolith is a mushroom-shaped intrusion of magma that forms when magma is injected between sedimentary layers and causes the overlying rocks to bulge upward.
