* Heat and Pressure: The igneous intrusion is extremely hot. This heat can cause the surrounding crustal rock to expand and become less dense. The magma itself also exerts pressure on the surrounding rock.
* Uplift and Deformation: The combination of heat and pressure can lead to the uplift of the surrounding crust. The rock may also deform and fold, creating visible geological features.
* Examples: This process is common in areas with active volcanism. For example, the formation of mountains like the Sierra Nevada in California is partly attributed to the intrusion of large granite bodies.
