Which process involves magma moving into pre-existing rock to form igneous rock?

Explanation:
Intrusion is the process where magma moves into pre-existing rock and then cools and crystallizes there to form igneous rock. When magma intrudes underground, it cools slowly, creating coarse-grained rocks like granite. If magma reached the surface, it would erupt as lava and form volcanic rocks after rapid cooling, but the description here centers on it moving into existing rock. Erosion and weathering break down rocks at the surface, not their formation, and metamorphism changes rocks through heat and pressure without melting.
