Metamorphic Rock

They are normally hard and durable, and resistant to weathering and erosion.

Metamorphic rocks at hot spots will form mostly by contact and hydrothermal metamorphism as a result of exposure to heat from magma and interaction with hot water respectively.

Slate is already a metamorpic rock. It is formed by the action of heat and pressure on shale. Further metamorphism may produce phyllite.

Metamorphic rocks form by rocks being changed while still in the solid state. If the temperature of a rock exceeds its melting point, it will melt and any rock that forms as a result will be considered igneous.

Yes, you can. Gneiss is quite similar to granite.

When you weld, you need a temporary marking solution so you use soapstone bars. soapstones can also come in round form. They are very brittle so you get either a bar-shaped or a round-shaped metal holder so it won't break. They generally come $1-$3 online or at a welding shop such as Wilson Products where I got mine.

They form when layers of minerals lay on top of each other

Contact Metamorphism: When magma comes in contact with other rocks it will heat them and change them into new rocks. This often happens around an igneous intrusion.

It's a compound. Only two things are mixed to make it.

All of them, as long as they are in the right conditions.

Metamorphic rocks that consist of only one mineral that forms large interlocking crystals often have a _____ texture.

The foliation is caused by the massive force of pressure and high temperature which results from mountain building processes caused by plate collisions. The heat and pressure combine to realign the existing minerals from a random orientation to one of parallel orientation, thus creating the visible lines or platy cleavages found in foliated metamorphic rocks. The lines of foliation are created perpendicularly to the force being applied.

Metamorphism is the process by which any kind of rock is changed into a metamorphic rock. Metamorphism uses heat and pressure to change the chemistry within a rock. An igneous rock will get "cooked" and look differently after the metamorphose. A sedimentary rock is composed by debris from older pre-existing rocks deposited in layers. These layers will become bent and the new rock will look "squeezed" after the metamorphose.

Examples of metamorphosed rocks:

Granite - Gneiss

Shale - Slate

Limestone - Marble

"Blue ridge" is not a specific enough name for us to be able to answer this question. There are many "Blue ridges" to be found on Earth. Please make your questions more specific. Include continent, country etc.

No. Dacite is an extrusive igneous rock.

Foliated rocks have layers in them. We often refer to the layers as Banding.

Weathering can break down metamorphic rocks into smaller fragments through physical and chemical processes, leading to the formation of sediment. This sediment can then become compressed and cemented to form sedimentary rocks. Additionally, weathering can alter the mineral composition and texture of metamorphic rocks, changing their original characteristics.

Both were created under extreme heat and can contain crystals or gems.

Lack of banding

Geological processes form rocks. Igneous rocks are made from magmas. Metamorphic rocks are made by changing the physical environment of a previously existing rock.

Amphibolite is a metamorphic rock. It forms when basaltic rock is heated to high temperatures under pressure. Without the added pressure the basaltic rock that would be yielded is green schist.
