Thermal metamorphism typically takes place in the presence of high temperatures, which can be caused by igneous intrusions or burial in deep crustal levels. It commonly occurs in regions with active tectonic activity such as convergent plate boundaries or hot spots, where heat from the Earth's interior is able to increase the temperature of existing rocks and minerals.
Contact metamorphism is least likely to occur at locations where there is little to no intrusion of magma near the Earth's surface. In areas with minimal igneous activity and no heat source to drive the metamorphic changes, contact metamorphism is less likely to take place. Generally, regions located far away from tectonic plate boundaries or volcanic hotspots are less prone to experiencing contact metamorphism.
Most geologic activity on Earth takes place along tectonic plate boundaries, where plates move and interact, leading to events like earthquakes, volcanic eruptions, and mountain building.
Igneous rock can become metamorphic rock through the pathways of regional metamorphism, where intense pressure and heat from tectonic forces transform the rock, or contact metamorphism, where it is altered by high temperatures from nearby magma intrusion.
Another geologic event that could take place is a volcanic eruption, where molten rock, ash, and gases are expelled from a volcano onto the Earth's surface. This event can lead to the formation of new landforms and potentially pose risks to nearby communities due to lava flows, ash fall, and volcanic gases.
As the plates grind against each other, it can lead to earthquakes, volcanic eruptions, and the formation of mountain ranges. The friction between the plates can cause stress to build up until it is released suddenly, resulting in these geologic events.

Only an intrusive igneous rock forms underground, but you can argue that all metamorphism occurs underground. The issue here is that when the metamorphism is thermal, often the ground it is under has only just been formed (i.e. a lava flow). To avoid confusion, only regional metamorphism can take place underground. The rocks formed by regional metamorphism and intrusive magma cooling are rocks with crystalline texture.
Metamorphism can take place in a solid state. The metamorphism can take place with or without any types of fluid activity, although, the majority is done with fluid activity.
Most metamorphism takes place deep underground, where high heat and pressure change the rocks, since both increase with depth.

Contact metamorphism is least likely to occur at locations where there is little to no intrusion of magma near the Earth's surface. In areas with minimal igneous activity and no heat source to drive the metamorphic changes, contact metamorphism is less likely to take place. Generally, regions located far away from tectonic plate boundaries or volcanic hotspots are less prone to experiencing contact metamorphism.
Metamorphism takes place primarily in the Earth's crust, where rocks are subjected to high temperatures and pressures, typically at depths of several kilometers. This process often occurs at tectonic plate boundaries, particularly in regions of subduction and continental collision. Additionally, metamorphism can occur in areas with intrusions of magma, where heat from the molten rock alters surrounding rocks.
