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.
The rock layer the dike cuts across is older
Granite is older
Lava that cuts across rock layers hardens to form a feature called a Dike.
A dike I got it right on a test
No, when magma forces itself BETWEEN rock layers it is called a sill. When the magma cuts THROUGH rock layers it is called a dike.
In fractures that cut across rock layers
Vein :mass of rock which occupy fissures in other rocks, Dike is sedimentary layer cuts across preexisting rocks.
A dike
an intrusive body of magma that cuts across layers of rock
Lava that cuts across rock layers hardens to form a feature called a Dike.
the type of thin pluton thats cuts across preexisting layers of rocks is Dike.
A body of magma that cuts through (and across) adjacent rock. Similar to a secondary vent but it does not strike through the surface. It then hardens and forms rock. It is always younger than the rocks which surround it.
A dike.
That would be a type of igneous intrusion known as a dike.

AnswerA dike is an intrusive body of magma that pushes its way across layers of sediments.A sill is an intrusive body of magma that pushes its way between layers of sediments.
No, when magma forces itself BETWEEN rock layers it is called a sill. When the magma cuts THROUGH rock layers it is called a dike.
When magma pushes into vertical cracks and cuts through layers across, igneous rocks called dikes are formed. Dikes are one form of plutons. An intrusive dike would form.
In geology, a dike is a type of rock formation that is formed when magma is injected into fractures in the Earth's crust and solidifies underground. Dikes are typically composed of intrusive igneous rocks such as basalt, granite, or dolerite.
