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.


When The walls of the grand canyon are made up of layers of sandstone a dike cuts across some of the layers when did the dike form?

The dike likely formed after the layers of sandstone, as it cuts across them. Dikes form when magma intrudes into existing rock layers and solidifies underground before being exposed at the surface through erosion. Therefore, the dike is a later geological event compared to the formation of the original sandstone layers in the Grand Canyon.


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.
