Sedimentary rock is first deposited in environments such as riverbeds, lakes, and oceans, where sediments accumulate over time. These sediments, which can include fragments of other rocks, minerals, and organic materials, settle in layers as water slows down. Over time, the weight of overlying materials compacts these sediments, leading to lithification and the formation of sedimentary rock.

The layer of sedimentary rock that was deposited first is typically the lowest layer in a sedimentary sequence, known as the "oldest" layer. According to the principle of superposition, in undisturbed sedimentary rock formations, the layers are arranged with the oldest at the bottom and the youngest at the top. This means that the first layer deposited is usually the one furthest down in the sequence. However, geological events like folding or faulting can complicate this arrangement.
Yes and No An igneous rock can not just "become" a sedimentary rock, it first has to be weathered and eroded at the surface of the Earth. The debris produced is then washed away as sediment and deposited elsewhere. This deposited sediment then gradually hardens into a new rock which is a sedimentary rock. Thus until igneous rocks are exposed in outcrop, they remain as igneous rocks.
Sedimentary rock is typically deposited in a geosyncline due to the accumulation of sediment over time. This process can result in the formation of various sedimentary rocks such as sandstone, shale, and limestone.
If eroded, deposited, compacted and cemented, it becomes clastic sedimentary rock.

By being first weathered into loose material (clast), then transported, then deposited, and then consolidated.
As sedimentary rock is deposited at over time, you can find fossils in it.

Broken pieces of sedimentary, igneous, or metamorphic rocks can be deposited into layers and cemented together to form sedimentary rock.
