Shale that is exposed to high temperature and pressure and turned to slate is an example of the metamorphic process.
Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.
Slate is metamorphosed shale.
mudstone and shale. These can become the metamorphic rock slate if exposed to high pressure and temperature.
The sedimentary rock gets transformed into metamorphic rock under the heat and pressure of mountain-building processes. Examples of metamorphic rocks formed from sedimentary rocks include marble from limestone and schist from shale.
Shale exposed to great pressure can form slate, a fine-grained metamorphic rock. The intense pressure and heat cause the clay minerals in the shale to recrystallize, resulting in a denser and more durable rock with distinct foliation.
Slate is the metamorphic rock that forms from shale after it is exposed to heat and pressure for a llllloooooonnnnnnnggggg time.
Shale that is exposed to high temperature and pressure and turned to slate is an example of the metamorphic process.
Slate is the metamorphic rock, formed from regional (heat and pressure applied) metamorphism on shale.
Slate is formed from the metamorphism of shale or mudstone. This process involves intense heat and pressure which causes the shale to recrystallize into a fine-grained, foliated rock with excellent cleavage properties.
Slate is the metamorphic rock formed from shale. A pile of mud can turn into shale (a fine-grained sedimentary rock) with relatively low pressure, about 3 mi (5 km) down into the earth. With more pressure and some heat, shale can transform into slate. Metamorphic rock found closer to Earth's surface, or produced by low pressure, characteristically splits or flakes into layers of varying thickness. This is called foliation. Slate is often used as roofing tiles and paving stones.
