Weathering is the decomposition of earth rocks, soils and their minerals through direct contact with the planet's atmosphere. Metamorphism is the solid-state recrystallisation of pre-existing rocks due to changes in heat, pressure, and/or introduction of fluids. SImply put, weathering is the break down of rock (wear and tear) and Metamorphism is rock changing due to Heat,Pressure, and Chemically active fluids
Slate is a fine-grained metamorphic rock formed from the low-grade metamorphism of shale or mudstone, while phyllite is a more intermediate-grade metamorphic rock formed from the metamorphism of slate. Phyllite has a more pronounced foliation and sheen due to increased metamorphic pressure and temperature compared to slate.
Regional metamorphism is the creation of metamorphic rock from large geographically significant processes like plate tectonics. Contact metamorphism is the creation of metamorphic rock from the proximity of an existing rock to a heat source provided by a plutonic intrusion.
metamorphism
Metamorphism.
The word "metamorphic" is the adjective form of the word "metamorphism. " An example of a sentence using the word "metamorphic" is "Metamorphic rocks are the product of a process called metamorphism, in which existing rocks and minerals undergo a transformation. "
Regional metamorphism
Schist is a metamorphic rock with medium to coarse grain size that typically forms from the metamorphism of shale or mudstone. Marble is a metamorphic rock primarily composed of calcite or dolomite minerals that forms from the metamorphism of limestone. Schist has a foliated texture, while marble has a non-foliated texture.
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.
Metamorphism, transformation...
Types of metamorphism are Contact Metamorphism Regional Metamorphism Cataclastic Metamorphism Hydrothermal Metamorphism Burial Metamorphism Shock Metamorphism (Impact Metamorphism)
A zone of contact metamorphism is called an aureole.
Dating a metamorphic rock can indicate the time since metamorphism occurred.
