Contact metamorphism generally occurs relatively close to the surface in a zone of contact between an intruding magma body and the country rock, which could be a sedimentary, igneous, or previously metamorphosed rock. Hornfels is a common resultant contact metamorphic rock.
Contact metamorphosis occurs when pre-existing rocks are altered primarily due to the heat from nearby molten magma or lava, resulting in localized changes. In contrast, regional metamorphosis affects larger areas of rocks due to high pressures and temperatures, often associated with tectonic processes such as mountain building. While contact metamorphism typically produces more localized and specific mineral changes, regional metamorphism leads to widespread alterations and the formation of foliated textures in rocks.
The Geological process of metamorphosis takes geological time scales (except thermal contact metamorphosis - contact with lava) - It is not clear what you are asking but it is not metamorphosis.
Contact metamorphism does not often produce the foliation caused by regional metamorphism
metamorphosis
Metamorphosis caused by deep burial of a whole (regional) slab of rocks.
Rocks tumbling down a mountain involve contact forces. As the rocks move, they come into contact with the surface of the mountain and other rocks, creating friction and impact forces. Additionally, gravity acts as a non-contact force that pulls the rocks downward, but the interaction during their descent is primarily characterized by contact forces.
When rocks come in contact with molten rocks from an igneous intrusion, the surrounding rocks may undergo contact metamorphism, where their mineralogy and texture are altered due to the heat and chemical reactions with the intruding magma. This can result in the formation of new minerals and textures in the rocks near the intrusion boundary.
Mountains are made of many different rocks. Such as sedimentary, ingenious and metamorphosis rocks.

Earth movements form metamorphic rocks by pressing, squeezing, and folding. Sometimes minerals are destroyed and new minerals are created
Rocks that we can see and touch are from the lithosphere and asthenosphere, created by erosion and sedimentation, solidified magma, or metamorphosis of a product of the first two.
Metamorphic rock is formed from another kind of rock under great heat and pressure. This process alters the mineral composition and texture of the original rock, creating a new type of rock. Examples of metamorphic rocks include marble, schist, and gneiss.
