Answer
Brief Explanations:
Intrusion is the process where magma is pushed up from within the Earth and forced into cracks or pushes rock out of the way. The principle of superposition is about the layering of rock - older layers at the bottom. Radioactive decay is related to the breakdown of unstable isotopes. Extrusion is when magma reaches the Earth's surface.
Answer:
A. Intrusion
