Minerals are aligned in the direction of stress.

Metamorphism occurs and they change to metamorphic rocks

contact metamorphism occurs when hot magma bakes rocks

The rocks constituent minerals can become perpendicularly aligned from pressure, they can change from hydrous minerals to non-hydrous minerals, or they can recrystallize into larger crytals from from heat. In the case of contact metamorphic rocks, there can also be a transfer of elements from the plutonic intrusions into the host rock.

Contact metamorphism occurs when rocks come in contact with molten magma far below the earths crust. hope this answer helped you :)

Metamorphism is a PROCESS. metamorphism is the process of change that occurs to rocks when they are subject to heat, pressure or both.

They grow by heat and pressure. (metamorphism, recrystallization).

What happens to rocks and minerals during physical weathering?

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.

Contact metamorphism occurs locally, next to igneous intrusions and along fractures that were in contact with hydrothermal fluids. Regional metamorphism occurs over very large areas, such as deep within the cores of rising mountain ranges, and generally occurs with the folding of rock layers. Both result in the formation of metamorphic rocks.

contact metamorphism is what happens when something is really hot. regional metamorphism on the other hand involves much larger packages of rocks.

magma comes in contact with other rocks, and the rocks melt and change

By melting and then solidifying. But there may be a process of metamorphism that takes place before melting occurs.

This type of rock metamorphism is literally called 'contact' metamorphism.If your doing a crossword or a one word answer just write 'contact'!Simple!

These rocks get their name from the Greek words 'meta' and 'morph', meaning 'change of form'. Metamorphic rocks are produced by the alteration of pre-formed rocks by pressure, temperature and migrating fluids, often in environments deep in the Earth's crust. Because of the severe conditions which rocks undergo during metamorphism, the original minerals may become unstable and change to maintain equilibrium with the new environment. This can involve changes in mineralogy (recrystallization of existing minerals or formation of new ones) and usually changes in texture from the original rock. Three main types of metamorphism are recognized. Regional metamorphism results from mountain-building events with large scale folding and burial of pre-formed rocks. Contact metamorphism is produced by direct heating of rocks around an igneous intrusion, baking the surrounding country rocks. Dynamic metamorphism occurs where large scale faulting breaks and deforms rocks next to the fault.

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. "

Cataclastic meta rocks are formed from rocks grinding past each other in fault zones. Burial metamorphism creates altered rock simply from overburden pressure. Contact metamorphism occurs from exposure to heat from an intrusive magma body. Regional metamorphism occurs from pressure and heat caused by tectonic forces.

All rocks can undergo metamorphism; sedimentary, igneous, and even metamorphic rocks.

marble is a metamorphic rock and was formed by regional or contact metamorphism it is a metamorphism of limestone and dolostone. the composition is calcite and/or limestone(sedimentry rock made od calcite)

The most common type of land metamorphism is Regional metamorphism. The most common rocks are slates, schists, and gneisses. This occurs within the folds of mountain belts and cratonic areas.

Large-scale regional (mainly pressure) metamorphism of sedimentary rocks originating from clay-forming minerals.

This question is worded strangely, but I think you are referring to Metamorphic rocks and metamorphism.

The process of cementation binds minerals together to form rocks. It occurs when dissolved minerals fill in the spaces between the sediment particles.
