Siccar Point is the location where the Scottish geologist James Hutton discovered the unconformity (now named after him) where tectonically disturbed and hence steeply dipping Silurian greywackes are overlain by horizontally bedded Devonian sandstones.

The rocks either fracture under the stress, or become compressed in different rocks known as "metamorphic".
Rocks at or near the surface are subjected to mechanical and chemical weathering which results in oxidation and hydration of their minerals and breaking into smaller pieces. Rock fragments and mechanically-weak weathered rocks may then be subject to erosion, i.e. to being carried away.
When rocks undergo weathering, they can form sedimentary rocks. Weathering breaks down rocks into smaller sediments, which then get compacted and cemented together to form sedimentary rocks.
All rock types can be changed through metamorphism.
Rocks at great depths are under high pressure and temperature due to the weight of the overlying rocks. This can cause the rocks to undergo changes in texture and composition, such as metamorphism, and can also influence the behavior of fluids within the rocks.

Metamorphic rocks are formed when existing rocks undergo intense heat, pressure, or chemical changes within the Earth's crust. These changes cause the minerals in the rocks to reorganize and form new structures, resulting in the creation of metamorphic rocks.

Sedimentary rocks are formed when pre-existing rocks, minerals, or organic material undergo weathering, erosion, transportation, and deposition. These sediments then undergo compaction and cementation to form solid rock layers.
stress and strain, resulting in deformation. This deformation can lead to the formation of faults, folds, and fractures in rocks. Over time, the rocks may undergo changes in their physical properties and structure due to these applied forces.
Both are types of rocks that form from the cooling and solidification of molten materials. They can both undergo changes due to heat and pressure, with igneous rocks forming from magma and metamorphic rocks forming from existing rocks that undergo metamorphism.

Answer: No, only ingenous rocks undergo crystallization. :)
As rocks undergo stress, they can deform, leading to changes in their shape and volume. This deformation can occur through processes like folding, faulting, or fracturing, depending on the type and intensity of the stress acting on the rock. Over time, these changes can result in the formation of geological structures such as mountains, valleys, and faults.
Metamorphic rocks form when existing rocks undergo changes in temperature and pressure due to processes such as tectonic plate movement, burial deep within the Earth's crust, or contact with hot intrusions. These changes cause the minerals in the existing rocks to recrystallize and reorganize, leading to the formation of metamorphic rocks.

It can undergo more metamorphism, creating a different metamorphic rock, or undergo retrograde metamorphism, which also creates a different metamorphic rock. Metamorphic rocks can undergo these changes due to increases or decreases in temperature and pressure.
