Dike

Real World Example

Imagine trying to fix a leaky roof by placing a strong piece of wood across the damaged area to stop the water from seeping through. Just like that piece of wood blocking the leak, a dike is formed when magma intrudes into cracks in the earth's crust and solidifies, cutting across existing rock layers. In this analogy, the roof represents the layers of rock, the leak is the crack or weakness in these layers, and the piece of wood is the hardened magma that forms the dike, effectively sealing the breach and providing a sturdy barrier.
