Slate is the metamorphic rock that forms from shale after it is exposed to heat and pressure for a llllloooooonnnnnnnggggg time.
It becomes hot and under pressure. At some stage, with sufficient heat and pressure it could become a metamorphic rock.
Metamorphic rock
Well, first before the sediment can become to a metamorphic rock, it has to create into a sedimentary rock or an igneous rock, Then the rocks go under the ground and is under tons and tons of pressure, which fosters heat build up, and this causes them to change.
because igneous' constant heat would melt it and water used to make sedimentary would break it with pressure or erode it
Marble.
under heat and pressure
If you apply shale with intense heat and pressure. you'll get slate. Now just apply intense heat and pressure to the slate an over time you'll get your schist
Schist
Gneiss is a metamorphic rock formed when intense heat and/or pressure is applied to it's parent rock schist.
The only real characteristic that metamorphic rocks share is that they are formed by heat and pressure. Granite warps and twists and becomes schist; shale is compressed and heated and becomes slate... etc.
Schist is a metamorphic rock. This type of rock has been changed because of great heat or pressure, or both
First it would change to Slate, but with increasing heat and pressure, it would eventually become Phyllite, then Schist, and finally Gneiss.
Schist and marble would be common examples.
When a rubber band is exposed to heat it contracts heat, meaning that sucks up all the heat and becomes smaller.
It would undergo metamorphism, if the heat and pressure are sufficient.
