Thermal metamorphism is a type of metamorphism that occurs due to the heat from a nearby igneous intrusion, leading to changes in the mineralogy and texture of rocks. Regional metamorphism, on the other hand, is caused by high pressure and temperature over a large area, typically associated with tectonic plate collision or subduction. The main difference lies in the scale and mechanism of metamorphic changes, with thermal metamorphism being more localized and regional metamorphism affecting larger regions.
Thermal metamorphism is caused by heat from a nearby magma intrusion which alters the rocks directly surrounding it, resulting in changes in mineralogy and texture. In contrast, regional metamorphism is caused by tectonic forces and pressure over a large area, transforming rocks over a broad region, typically leading to the formation of foliation and new minerals.
thermal is when the rock is metamorphosed by heat more than pressure.
regional is the opposite.
so if a rock is close to the surface and gets metamorphosed next to a pluton, it is mainly heat (its not very deep, so there is not a lot of pressure, but it gets a lot of heat from the pluton).
but if a rock is very deep and far from any magma, it will be under a lot of pressure, but not a lot of heat. so thus, regional metamorphism.

What are the types of rock metamorphism?
The main types of rock metamorphism are contact metamorphism, regional metamorphism, and dynamic metamorphism. Contact metamorphism occurs when rocks are altered by heat and pressure from nearby magma. Regional metamorphism happens on a larger scale due to tectonic forces and deep burial. Dynamic metamorphism results from intense pressure along fault lines.
Compare contact thermal metamorphism and regional dynothermal metamorphism and the types of rocks that result from each?
Contact thermal metamorphism is localized and results from the heat of a nearby igneous intrusion. The rocks that form from this process are typically hornfels, formed by the recrystallization of pre-existing rock. Regional dynothermal metamorphism, on the other hand, occurs over a wide area due to deep burial and tectonic forces. Rocks resulting from this process are typically schist and gneiss, which exhibit strong foliation and banding due to the intense pressure and heat.
What type of rock is meta-conglomerate?
Meta-conglomerate is a metamorphic rock that forms from the metamorphism of conglomerate, which is a sedimentary rock composed of rounded gravel and pebbles. The process of metamorphism changes the texture and mineral composition of the conglomerate, resulting in meta-conglomerate.
What are three agents of metamorphism?
The three agents of metamorphism are heat, pressure, and chemically active fluids. Heat causes minerals to recrystallize, pressure changes the mineral structure, and chemically active fluids can introduce new elements into the rock.
What geologic setting does thermal metamorphism take?
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.

Are rocks formed due to thermal metamorphism soft or hard?
Rocks formed from thermal metamorphism are very hard. An example is hornfels. Just search thermal metamorphism and/or hornfels and you'll see some nice explanations on the web.
What is the difference between thermal and radioactive radiation?
There is no difference
What is 2 types of metamorphic rocks?
Metamorphic rocks are formed by the process of extreme heat, pressure and other chemicals. Two types of metamorphism are dynamic which makes the pressure and extreme heat and thermal which is caused by the heat of magma from a volcanic eruption.
What type of rock can only form deeply underground?
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.
Which type of metamorphic rock means formed in fire?
Thermal metamorphism.
