Sedimentary rocks that are originally deposited in flat horizontal layers are known as "stratified" or "bedded" rocks. These layers, or strata, form through the accumulation of sediment over time, often in environments like riverbeds, lakes, or ocean floors. The horizontal arrangement indicates that they have not been significantly disturbed by tectonic forces after their formation. This layering can reveal valuable information about the Earth's history, including past environments and geological events.

Principle of cross-cutting relationships. by applying the cross-cutting principle, you can see that fault A occurred after the sandstone layer was deposited because it "broke" the layer..
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 layers found in sedimentary rocks are called strata. These are horizontal layers of sediment that have been deposited over time and then compacted and cemented together to form rock. Each layer represents a different time period in Earth's history.
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.

Incorrect. The bottom of a sedimentary layer was deposited before the top. Imagine pouring different colors of sand in a clear vial one layer at a time and alternating colors. The color (or layer) on the bottom of the vial was deposited by you very first and the layer on top was last to be deposited.
The law you are referring to is known as the Law of Superposition. This principle states that in any undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom, with younger layers deposited on top. As a result, each layer of rock is older than the layer above it and younger than the layer below it, providing a chronological framework for understanding geological history.
It is called sedimentation.
The one closest to the surface because rock layers are laid down one on top of another.
Law of Superposition: In an undisturbed sequence of rock layers, the youngest layer is at the top and the oldest is at the bottom. Law of Original Horizontality: Sedimentary layers are originally deposited in horizontal layers. Law of Lateral Continuity: Layers of sediment initially extend laterally in all directions until they thin out or reach a barrier. Law of Cross-Cutting Relationships: If a geological feature cuts across another layer, it is younger than the layer it cuts through.
