How are contact and hydrothermal metamorphism different from each other?

There different from each other because contact metamorphism is a local effect that occurs when molten rock meets solid rock, but on the other hand hydrothermal metamorphism occurs when very hot water reacts with rock, altering its mineralogy and chemistry.

What are the types of rock metamorphism?
Types of metamorphism are Contact Metamorphism Regional Metamorphism Cataclastic Metamorphism Hydrothermal Metamorphism Burial Metamorphism Shock Metamorphism (Impact Metamorphism)
How is contact metamorphism different. from regional metamorphism?
contact metamorphism is what happens when something is really hot. regional metamorphism on the other hand involves much larger packages of rocks.

What is Contact metamorphic?
Contact Metamorphism: When magma comes in contact with other rocks it will heat them and change them into new rocks. This often happens around an igneous intrusion.
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.
When rocks stack up on each other what metamorphism can occurr?
Burial metamorphism.
What is the major difference between metamorphism and metasomatism?
Metamorphism is the solid-state recrystallization of pre-existing rocks due to changes in physical and chemical conditions, primarily heat, pressure, and the introduction of chemically active fluids. Mineralogical, chemical and crystallographic changes can occur during this process. Changes at or just beneath Earth's surface due to weathering and/or diagenesis are not classified as metamorphism.Three types of metamorphism exist: contact, dynamic and regional. Metamorphism produced with increasing pressure and temperature conditions is known as prograde metamorphism. Conversely, decreasing temperatures and pressure characterizeretrograde metamorphism.Metasomatism is the chemical alteration of a rock by hydrothermal and other fluids. Metasomatism can occur via the action of hydrothermal fluids from an igneous or metamorphic source.In the igneous environment, metasomatism creates skarns, greisen, and may affect hornfels in the contact metamorphic aureole adjacent to an intrusiverock mass. In the metamorphic environment, metasomatism is created by mass transfer from a volume of metamorphic rock at higher stress andtemperature into a zone with lower stress and temperature, with metamorphic hydrothermal solutions acting as a solvent. This can be envisaged as the metamorphic rocks within the deep crust losing fluids and dissolved mineral components as hydrous minerals break down, with this fluid percolating up into the shallow levels of the crust to chemically change and alter these rocks.Because metasomatism is a mass transfer process, it is not restricted to the rocks which are changed by addition of chemical elements and minerals or hydrous compounds. In all cases, to produce a metasomatic rock some other rock is also metasomatised, if only by dehydration reactions with minimal chemical change.
How many types of metamorphism occur in earth's crust?
Two types of metamorphism occur in earth's crust. One is when small volumes of rock come in contact with magma. And the other is when large amounts of the earth's crust are effected by heat and pressure
Where is the dynamic metamorphism located?
Contact metamorphism is defined as metamorphism in which the mineralogy and texture of a body of rock are changed by exposure to the pressure and extreme temperature associated with a body of intruding magma. It can either happen deep underground or at the Earth's surface.
When rocks stack up on each other what type of metamorphism can occur?
Regional metamorphism can occur.
