Shale is formed as a result of many processes. The first process involves the weathering and erosion of existing silicate rock, usually igneous or metamorphic in nature, and what would normally appear in a weathering mountain range. The weathering of this rock creates clay and silt sized particles which are transported down slope by the erosion from wind, moving water, gravity, and ice. These small particles are carried the farthest from their point of origin, and settle out from suspension in the water or wind in a process known as deposition. As more and more sediment layers are added over great lengths of time, the particles of sediment are compacted by the weight from above and the clay particles become loosely interlocked into a rock with thin depositional layering - shale.

What is similarities between shale and slate?
Slate and shale have the same make-up. Slate is formed from sedimentary shale by pressure and heat. Wet shale has the same smell that wet slate has.
Is shale a mixture of clay and silt?
It is more accurate to say it is formed from clay and silt.
Was slate once shale?
Yes, slate was once shale. Shale is a sedimentary rock formed from the compaction of mud and clay, while slate is a metamorphic rock that forms from the metamorphism of shale. The process of metamorphism involves heat and pressure, which transforms the shale into slate by aligning the minerals and creating a foliation (layering) within the rock.
Where do shale rocks form?
Shale is sedimentary, and is normally formed at the bottom of bodies of water. It is today found on mountaintops sometimes, but that is because of the "pushing up" action of plate tectonics. It is most commonly found at ground level, though.
Is sandstone limestone and shale are all examples of igneous rock?
Sandstone, Limestone and Shale are all examples of sedimentary rock, formed by layer after layer of different types of water born sediment laid down over millions of years and compressed into rock. The different types of sediment determine which type of rock is formed, obviously sand being the main component of sandstone, mud can form shale. Igneous rock is rock formed by volcanic processes, different minerals in the molten rock will determine it's type, such as granite. Metamorphic rock is the third type of rock formed by extreme pressure and heat upon sedimentary rock, marble being formed from limestone, slate from shale.
How are shale beaches formed?
Shale beaches are formed from the deposition of sediment form nearby shale cliffs which are eroded. The shale can also be deposited at a beach due to longshore drift.
Where was shale formed?
Shale forms in layers of sandstone or lime.
Rocks formed from shale?
Shale can metamorphose through heat and pressure into slate.
What is a metamorphic formed from shale?
Slate
What is sedimentary rock formed by deposit of shale?
Slate is the metamorphic rock, formed from regional (heat and pressure applied) metamorphism on shale.
Is granite formed from the metamorphism of a shale?
No. The metamorphism of shale forms slate. Granite is formed when high-silica magma cools underground.
Is a rock called shale formed from the skeletons of the ancient coral animals?
No, shale is a type of sedimentary rock formed from the accumulation of silt and clay particles. It is not formed from the skeletons of ancient coral animals, which are typically preserved in rocks such as limestone.
What is slate formed by?
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.
What is a dark sedimentary rock formed by compression of layers of clay-rich sediment?
Shale is made from layers of mud and clay pressed together. :)
What is a metamorphic rock formed from a shale?
Slate. Slate is a low grade metamorphic rock derived from shale or mudstone.
What sedimentary rock is formed from thin layer of clay compacted very tightly together?
This is Shale, a Sedimentary rock.
What is similarities between shale and slate?
Slate and shale have the same make-up. Slate is formed from sedimentary shale by pressure and heat. Wet shale has the same smell that wet slate has.
