shale is fine
No, all sedimentary rocks can be eroded and shale is characterised by very fine laminations. Hence the shale breaks easily along these planes of weakness and is therefore easily eroded.
The rock you are referring to is shale. Shale is a fine-grained sedimentary rock composed of compacted clay and silt particles. When subjected to intense heat and pressure, shale can undergo metamorphism and transform into slate. This process of metamorphism causes the clay minerals in shale to recrystallize, resulting in the characteristic foliated texture of slate.
The lifting and removal of fine sediments by wind is called deflation. It is the process of lowering the land surface.
No. Limestone and shale are sedimentary rocks the form by different processes. Limestone is a biological sedimentary rock that forms from the carbonate shells of organisms. Shale is a clastic sedimentary rock the forms from the settling of fine-grained particles of mostly silicate minerals.
Shale is a sedimentary rock formed from extremely fine grains of mud. They are typically about 0.004 mm in diameter.

You don't make oil from shale, you extract oil from shale. The shale acts like a sponge, sometimes the shale is so porous that the oil can be squeezed or sucked out, otherwise it can be extracted by crushing and heating the shale.
The texture of shale is fine grained
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.
because when water slow down at the low area at the begining of the fine sediments are deposited in the delta river
fine-grained sediment
Shale is layered, the layers being very fine grained.

The fine soil that was deposited at the mouth of a river in Egypt was called silt.
Very fine sediments are known as silt.
