A dike is a type of rock that cuts across the layers of its surroundings. They're often made of magma, but sediments can also form dikes. If a rock cuts along the layers of its surroundings, it's a sill.

Which is older a dike or the rock layers the dike cuts across?

Dikes are always younger than the surrounding rock layers. The same holds true for any kind of intrusion. It will always be younger than anything that it is intruding into. To put it simply, you can't force an object into a bed of rock unless the bed of rock is already there.


If a dike is present within a rock outcrop what is its age relationship with the other rock layers?

The dike is younger than the rock layers it intrudes into. Dikes form when molten rock (magma) is injected into fractures in existing rock layers and then solidifies, cutting across the surrounding rock. This means that the dike is a later geological event compared to the layers it cuts through.


What forms across rock layers?

A dike.


What is a Dike formed of?

Intrusive igneous rock.


A sheet of igneous rock that protrudes into the surrounding layers of rock?

It is called a dike.


A sheet of igneous rock that protrude into the surrounding layers of rock?

It is called a dike.


Is a dike a intrusive ingneouse rock or a extrusive rock ingneouse?

A dike is an intrusive igneous rock. It is a vertical intrusion that is usually associated with a central magma chamber. It is intrusive because it usually does not reach the surface. When a dike does reach the surface, the magma it countains erupts and forms an extrusive lava flow.


What forms when lava flows vertically a layer of rock?

What is the definition of dike in science?

In science, a dike is a sheet of rock that cuts across the structure of adjacent rock layers. Dikes are formed when magma intrudes into existing rock layers and solidifies. They are often made of igneous rock and can vary in thickness and length.


What are the most important rock types in geology?

Some of the most important rock types in geology are Igneous Rock & Metamorphic Rock.


Is dike a type of lava flow?

A dike is not a type of lava flow, but rather a sheet-like intrusion of igneous rock that cuts across existing rock layers. Dikes form when molten rock (magma) is injected into fractures in the Earth's crust and crystallizes before reaching the surface.


Does a dike form when magma forces itself between rock layers and hardens?

Yes, a dike forms when magma intrudes into existing rock layers and solidifies. As the magma cools and solidifies underground, it creates a vertical or near-vertical sheet-like body of igneous rock that cuts across the existing rock layers.
