Magma rises from the earth to form dikes and sills
Dikes and sills may form when magma rises and bulges Earth's crust.
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.
Dikes, sills, and volcano necks are intrusive igneous features formed from magma that solidified beneath the Earth's surface. Dikes are vertical or near-vertical intrusions, sills are horizontal intrusions, and volcano necks are vertical conduits that fed ancient volcanoes. Batholiths are large, deep-seated intrusive bodies that often form the cores of mountain ranges. They are generally larger in size and represent a more massive intrusion compared to dikes, sills, and volcano necks.
Volcanic necks are solidified magma that fills the vent of an extinct volcano. Dikes are vertical or near-vertical rock formations that form when magma is injected into fractures and solidifies underground. Sills are horizontal rock formations created when magma is injected between layers of existing rock.
Sills and dikes are both intrusive igneous rock formations that form when magma solidifies underground. The main difference between them lies in their orientation: sills are horizontal intrusions that form between rock layers, while dikes are vertical intrusions that cut across existing rock layers. An example of a sill is the Palisades Sill located in New Jersey, USA, and an example of a dike is the Giant's Causeway in Northern Ireland.
When magma flows horizontally, it can form igneous rock formations called dikes or sills. Dikes are vertical intrusions, while sills are horizontal intrusions. These structures are formed when magma solidifies within preexisting rock layers.
When magma hardens between layers of rock, it forms intrusive igneous rock structures known as dikes or sills. Dikes cut across the existing rock layers, while sills form parallel to them. These formations are typically formed when magma solidifies underground before reaching the surface.
The four basic types of plutons are batholiths, stocks, dikes, and sills. Batholiths are large masses of intrusive igneous rock that form deep underground, while stocks are smaller intrusions. Dikes are tabular bodies of igneous rock that cut across existing rock layers, and sills are tabular bodies that intrude between existing rock layers.

Dikes are tabular intrusions that cut across existing rock layers. Sills are tabular intrusions that form parallel to existing rock layers. Laccoliths are mushroom-shaped intrusions with a flat base and a dome-like top. Batholiths are large intrusive rock bodies that cover at least 100 square kilometers in surface exposure. Volcanic necks are columnar intrusions that form when magma solidifies in a volcano's vent.
