Sedimentary rock formations are those which are formed by layer upon layer of sediment being laid down by natural forces. It is the stone in which history is hidden.

When organisms died in a river or stream of some sort, they are covered in a layer of sediment, as time gos by the sediment hardens and is covered by another layer of sediment and so on.
sediment gathers up then the water in the sediment starts to evaporate. Compaction and Cementation happens then forms layer after layer.

A mold and cast fossil is and exact stone replica of an organism but it is formed like this. The first layer of sediment hardens and forms a mold. then a new layer of sediment fills in the mold and hardens. That is the cast.
First, a thin layer of sediment hardens and forms a mold. Then, what is known as a cast is when a new layer of sediment fills in the mold breaking down the creature/ animal/fossil.
It is where a layer of underground water is sandwiched between layers of sediment and rock.
We use the term deposition to describe the process by which sediment is laid down in a body of water. The sediment is said to have been deposited at the bottom of the body of water, and more may follow to build a layer of sediment.
