Question

Compare and contrast dikes and sills.

Solution

Verified

If there are fractures or cracks in the crust of a volcanic region, the magma will force its way through the surface. This event will likely form a land feature called a dike. Dikes are formed when magma solidifies vertically across rock layers.

On the other hand, sills are formed when the magma pushes its way toward the surface. They are intrusions that are formed when the magma goes between horizontal layers of rock.
