How can you tell a metamorphic rock from another type?
Metamorphic rocks are rocks that have become changed by intense heat or pressure while forming. One way to tell if a rock sample is metamorphic is to see if the crystals within it are arranged in bands. Examples of metamorphic rocks are marble, schist, gneiss, and slate.
How can a metamorphic rock become a different type of metamorphic rock?
Metamorphic rocks are formed by tremendous heat, great pressure, and chemical reactions. To change it into another type of metamorphic rock you have to reheat it and bury it deeper again beneath the Earth’s surface.
Which is the best way to describe a metamorphic rock?
Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture.
How do you test for metamorphic rocks?
Method 1 of 2: Metamorphic rocks tend to have more luster than igneous or sedimentary rock. In the light, you should be able to tell whether the rock has an overall shimmery quality to it. Not all metamorphic rocks have luster or shiny grains. “Non-foliated” rocks are often opaque and dull in color.
Why does a metamorphic rock can change into another metamorphic rock?
Rocks change during metamorphism because the minerals need to be stable under the new temperature and pressure conditions. The need for stability may cause the structure of minerals to rearrange and form new minerals. Ions may move between minerals to create minerals of different chemical composition.
Which one of the following is a metamorphic rock?
Some examples of metamorphic rocks are gneiss, slate, marble, schist, and quartzite.
What four characteristics determine the type of metamorphic rock?
Factors that Control Metamorphism
- Chemical Composition of the Protolith. The type of rock undergoing metamorphism is a major factor in determining what type of metamorphic rock it becomes.
- Temperature.
- Pressure.
- Fluids.
- Time.
- Regional Metamorphism.
- Contact Metamorphism.
- Hydrothermal Metamorphism.
