Metamorphic rocks may display foliation, which is the layering, banding, or platiness that is associated with the rearrangement of mineral crystals due to directional pressure. Examples of foliated metamorphic rock include schist, slate, and gneiss.
Some minerals are typically formed due to the metamorphism of existing rock, and include those minerals that form due to the loss of water. When minerals that contain water can no longer exist due to heat and pressure, new minerals form. Garnet is a non-hydrous mineral that is often associated with metamorphic rock.
Metamorphism in rock can also manifest itself by the replacement of existing minerals by other minerals due to the invasion of the host rock by heated fluids which are created by a nearby magmatic intrusion.
Metamorphic rocks can also display a recrystallization and interlocking crystalline structure that is common when limestone or dolostone is metamorphosed into marble, or sandstone is metamorphosed into quartzite.

What physical characteristics of the bedrock are responsible for the oldest rock remaining at the highest elevation
List at least 3 characteristics that identify a metamorphic rock and explain why the rock has taken on that characteristic Also please list 3 characteristics that identify a sedimentary rock but not?
not sure
What physical characteristics of the bedrock are responsible for the oldest rock remaining at the highest elevation?
What physical characteristics of the bedrock are responsible for the oldest rock remaining at the highest elevation
What characteristics are most common in sedimentary rock?
they have fossils.
What are the characteristics of wind that can significantly alter a rock?
because they can carry on
What is the metamorpic rock for sandstone?
Quartzite is the metamorphic rock for sandstone.
Is calcits a metamorpic rock sedementary rock or igneous rock?
calcite is a mineral.
When metamorpic rock is eroded deposited and cemented what does it turn into?
Sedimentary rock.
Does weathering change metamorpic rock to sediments?
yes
What are the three rocks that make the earth made of?
igneous rock, metamorpic rock and sedimentary rock
The word metamorpic means?
Rock that has undergone transformation by heat or pressure
Is a metamorpic rock formed from shale?
yes, it's slate. it goes from shale to slate to phyllite to mica schist.
How does metamorpic rocks form?
Metamorphic rocks are formed from an existing rock (of any of the three types) being subjected to a combination of heat and pressure.
What s does slate turn into if heated and squashed?
Slate is already a metamorpic rock. It is formed by the action of heat and pressure on shale. Further metamorphism may produce phyllite.
Is porphyry igneous sedimentary or metamorpic?
its igenoeus
How dos metamorpic rocks turn into chalk?
They don't.
Can metamorphic rock be changed by heat or pressure into a different kind of metamorpic rock?
Yes. Slates can be metamorphosed into phyllite, which in turn can become schist, which can finally become gneiss before melting entirely. The exact type of rock and mineral content depends on the temperature and pressure conditions of its formation.
