sills
When magma hardens inside the Earth's crust, it can form vertical columns known as dikes, and horizontal layers called sills. Dikes form when magma cuts through pre-existing rock layers, while sills are formed when magma intrudes between existing rock layers.

Intrusive igneous rock.
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
a type of rock that forms when magma cools and hardens very slowly deep in earths crust...

Magma that hardens within the Earth's crust is called intrusive igneous rock. This type of rock forms when magma cools and solidifies beneath the Earth's surface, resulting in the formation of intrusive features like batholiths, dikes, and sills.
When magma cools at the surface of the Earth, it cools very quickly and hardens on the Earths crust. However, it continues flowing underneath, forming interesting textures.
igneous rocks come from inside the earths crust. Usually through volcanoes, or fissures

The Earths crust is approximately 650 km deep.
