It is more accurate to say it is formed from clay and silt.
Shale rocks turn into clay. The pressure make shale into clay.
clay, sand, and silt make up inorganic material in soil
Water deposits the clay particles in thin, flat layers.
the type of rock made mostly from clay is the shale rock
It smells like clay because that is what it's made out of.
shale
Silt and clay size sediments form shale.

Silt and clay size sediments form shale.
No. Shale forms from clay and silt, which are much finer than the sand that forms sandstone.
Shale rocks are formed in the deep waters of swaps, oceans and lakes where the water is still and the fine clay and silt particles are able to settle to the floor. Shale rocks can easily erode due to weathering.
its called clay loam. A true loam is approximately 40% each of sand and silt and 20% clay. This mineral mixture should be 92% of your soil and 8% organic material for your best growing mixture.
This sedimentary rock is shale. Proof of this is in the introduction of this WikiPedia article: http://en.wikipedia.org/wiki/Shale G'day _______________________________________________________________________ PS: Forgive me, but this sounds almost exactly like the question from the "Taken for Granite" sheet, and judging by how recent the question is, I think that you could've gotten this answer if you typed it in google. --Chewy (if you are who I think you are, you'll get who I am)
Yes. It is made out if clay. The difference between just clay and shale is that the shale consists of compacted clay. Because of compaction, the clay particles (which are flaky) tend to align themselves resulting in varying degrees of fissility. If shale is even more compacted, it will turn into a slate, which is no longer a sedimentary but a metamorphic rock.
Shale is a clastic sedimentary rock formed of clay and silt sized eroded particles that are a result of both physical and chemical weathering. The clay minerals, however are the result of chemical weathering of feldspars.
They are all sedimentary rocks. Limestone is formed from calcium-rich sediments, such as deposits of deceased shellfish, shale forms from clay and/or silt and sandstone forms from sand.
I would not think that it does because silt is a mixture of clay and rock . Wich would not make the soil fertile .
