1. What is a metamorphic rock?
2. How do metamorphic rocks form?
3. Where are some places that metamorphic rocks form?
4. What is metamorphic grade?
5. What is a parent rock (protolith)?
6. What is foliation?
7. How would you tell the difference between a marble, a schist, and a slate?
Thank you!
Homework Answers
1) rock formed due to change in pressure, temperature and chemical conditions of preexisting rock is called metamorphic rock
2) physical and chemical alteration of the preexisting rock (sedimentary, igneous or metamorphic) due to change in pressure and temperature conditions leads to formation of metamorphic rock
3) some places are - subduction zone, mountain building, duke or sill intrusion, batholith intrusion, faulting or folding region etc
4) intensity by which the parent rock has changed to a new rock during metamorphism is called metamorphic grade.
5) unmetamorphosed rock from which metamorphic rock forms due to metamorphism process is called protolith
6) layer in metamorphic rock with width less then 1m along which the rock splits into thin sheets is called foliation.
7) marble is a homogenous composition rock so it will show no foliation, schist medium to high grade metamorphic rock which show very good foliation due to presence of mica in significant amount. Slate is low grade metamorphic rock and will show poor Foliation

Metamorphism occurs when _____. mountain ranges are lifted up and eroded. rocks are heated to such a high temperature that they begin to melt. water evaporates from a large body of water at the surface of Earth. solid rock changes in composition and/or texture without the mineral crystals melting. At what temperature will metamorphism begin? 200 degrees Celsius 3,000 kbars 1,000 bars 2,000 degrees Celsius Differential stress (pressure) can cause _______. cause minerals to grow larger cause new minerals to...

The textures of igneous rocks, sedimentary rocks, and metamorphic rocks are all described with different terminology. That is, you cannot describe the texture of a sedimentary rock with the terms used to describe textures of igneous rocks. Bearing this in mind, please sort the terms below pertaining to rock textures into the three rock classes. lgneous rocks have textures that are either comprised of interlocking crystals, or textures that resulted from the cooling of hot liquid material. Sedimentary rocks have...
