What are some examples of metamorphism?
Examples of metamorphism include the formation of marble from limestone, the transformation of shale into slate, and the alteration of sandstone into quartzite. Metamorphism is the process by which rocks are changed by heat, pressure, or fluids, resulting in new mineral compositions and textures.
Example of a sedimentary rock that changes into igneous rock?
When sedimentary rock such as breccia gets buried deep within the earth, it changes into metamorphic rock. Metamorphic rock then can be changed into magma and reintroduced as igneous rocks, such as rhyolite or granite.
What results when rocks come in contact with molten rocks such as those in an igneous intrustion?
When rocks come in contact with molten rocks from an igneous intrusion, the surrounding rocks may undergo contact metamorphism, where their mineralogy and texture are altered due to the heat and chemical reactions with the intruding magma. This can result in the formation of new minerals and textures in the rocks near the intrusion boundary.
Are rocks that are changed by metamorphism more or less dense?
Rocks that undergo metamorphism can become either more or less dense, depending on the specific changes that occur. For example, the recrystallization of minerals during metamorphism can often lead to an increase in density, while the introduction of new minerals or pore spaces can result in a decrease in density.
How does the process of metamorphism lead to the formation of metamorphic rocks?
Metamorphism is the process where existing rocks are changed by heat, pressure, or fluids. This process causes the minerals in the rocks to rearrange and form new crystals, creating metamorphic rocks.
Sandstone and basalt are changed by heat and pressure to form?
Sandstone is changed into quartzite and basalt is changed into schist or gneiss through the process of metamorphism.
What does sandstone change to?
That depends on what happens to it. If it is sufficiently heated and compressed it will metamorphose to quartzite.

How can sandstone rock be changed into different sandstone rock?
by chemicals

The makeup of rocks is changed during?
The make up is changed when the mineral composition undergo metamorphism.

Sandstone and basalt can be changed by heat pressure to form?
Sedimentary rocks
Why can the chemical composition of rock be changed during metamorphism?
It is an open system; atoms can move into and out of the rock.
When rocks over a large area are changed by heat or pressure the process is called what?
regional metamorphism
Are rocks that are changed by metamorphism more porous or less?
Than?? Marble certainly isn't porous.
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.
