Some questions about metamorphic rocks that could be explored include: How do different types of pressure and temperature affect the formation of metamorphic rocks? What are the key minerals found in metamorphic rocks and how do they indicate the rock's history? How do metamorphic rocks differ from igneous and sedimentary rocks in terms of their formation processes and characteristics?
What else can I help you with?
Does metamorphic rocks have a higher porosity than sedimentary rocks?
No, sedimentary rocks generally have higher porosity than metamorphic rocks. Sedimentary rocks are formed from the accumulation of sediments, which can leave pore spaces between grains. Metamorphic rocks, on the other hand, have been subjected to heat and pressure, which can close up or reduce the pore spaces, leading to lower porosity.
What classification of metamorphic rocks would include whether they are?
Foliated or non-foliated. Foliated metamorphic rocks have a layered or banded appearance due to the alignment of minerals, while non-foliated rocks do not exhibit this feature.
What was gneiss before it undertook heat and pressure?
A mixture of sand and clay, mudstone, metamorphose (process of changing from one type of rock into a metamorphic rock) into gneiss rocks or schist rocks. The mudstones would change under heat and pressure to make the new Metamorphic rocks.
Are metamorphic rocks valuable?
It would depend on which metamorphic rock. Slate is in demand as a high-end roofing product and paver stone. Marble is used in sculpture, countertops, and flooring. Anthracite is considered the premier coal type. Most rocks, in fact, have some sort of economic usefulness; some more than others.
Does it take millions of years to form a metamorphic rock?
No, metamorphic rocks form over thousands to millions of years through the intense heat and pressure acting on existing rocks. The exact time it takes depends on the specific conditions present during the metamorphic process.
What is rock that is changed by heat pressure or chemical change?
Metamorphic rocks have been changed by heat or pressure. This can be a change in size, shape, or arrangement of minerals.
Is gneiss metamorphic?
A gneiss is a metamorphic rock. Metamorphic rocks are created by the alteration of rocks by heat and pressure. Therefore, a gneiss may be created from an igneous rock in which case it would be called an orthogneiss.
Can metamorphic rocks be created by melting?
Nope, because they are created when the Earth pressurizes and heats it (but not to the point of melting). Igneous rocks are created when rocks melt.
Can metamorphic rocks from from other metamorphic rocks?
Yes. Most likely it would become a metamorphic rock of higher grade. Slate is a low grade metamorphic rock. With increased heat and pressure it will become schist, a high grade metamorphic rock.
What 2 rocks are formed from all 3 kinds of rocks?
I would say Igneous and Metamorphic rocks.
Gneiss and slate are what type of rocks?
Nonfoliated metamorphic rock would be:Quartzite - composed of the mineral quartz; metamorphosed sandstoneMarble - composed of the mineral calcite; metamorphosed limestone
What crystalline structure would a metamorphic rock have?
they have rocks and minerals
Would you be less like to find fossils in metamorphic rocks than in sedimentary rocks?
Yes.
Does metamorphic rocks have a higher porosity than sedimentary rocks?
No, sedimentary rocks generally have higher porosity than metamorphic rocks. Sedimentary rocks are formed from the accumulation of sediments, which can leave pore spaces between grains. Metamorphic rocks, on the other hand, have been subjected to heat and pressure, which can close up or reduce the pore spaces, leading to lower porosity.
Why aren't you likely to find a fossil in metamorphic or igneous rocks?
the fossils would be turned into another rock if it was in a metamorphic rock or igneous rocks. it requires a blanket of sediment
A classification of metamorphic rocks would inculde whether they are?
foliated and nonfoliated
What type of rocks and rock formation would you find in India?
Some of the types of rocks and rock formation that someone would find in India would be sedimentary rocks, metamorphic rocks, igneous rocks, peak, and stack rocks.
