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.

The youngest layer of sedimentary rock is typically found at the top of a sedimentary rock sequence, as it is the most recently deposited layer. This layer is usually exposed on the Earth's surface, such as in river valleys or coastal areas, where erosion may have removed older layers above it.
The layer of rock formed from sediments deposited on land is called sedimentary rock. This type of rock forms from the accumulation and compression of sediments, such as sand, silt, and clay, over long periods of time. Examples of sedimentary rocks include sandstone, shale, and limestone.
In an undisturbed layer, the principle of superposition helps determine the order of deposition. According to this principle, in any sequence of sedimentary rock layers, the oldest layers are at the bottom, and the youngest layers are at the top. Therefore, by examining the vertical arrangement of the layers, geologists can infer which layers were deposited first.
Before a rock layer can be deposited, the area must undergo erosion and weathering. This breaks down existing rocks into sediment which can then be transported and deposited in a new location. The process of deposition occurs when the sediment settles into a new location and forms a layer over time.

As sedimentary rock is deposited at over time, you can find fossils in it.
Sandstone is a common sedimentary rock that is formed from the accumulation and compaction of sand deposits. It is characterized by its coarse texture and typically contains grains of sand cemented together by minerals like quartz or calcite.
