The Rock Layer has to harden first of all before it can be deposited.
The topmost rock layer is the one that was deposited last, as rock layers are typically deposited in a vertical sequence with the oldest layers at the bottom and the youngest layers at the top.

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 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.
Yes, a younger layer of sedimentary rock can be found beneath an older layer due to geological processes such as faulting, folding, or erosion followed by deposition. For instance, if tectonic activity pushes older rock layers upwards, younger sediments can be deposited on top of them, or if an area undergoes significant erosion and then new sediment is deposited, the sequence can be inverted. This phenomenon is often seen in complex geological formations where layers have been disturbed.

A rock layer can cause a gap in the geologic record through erosion, where the layer is removed by natural processes. Alternatively, non-deposition can also create a gap when no new sediments are deposited, leaving a break in the rock layers.

A missing layer in a rock layer sequence could be due to erosion or non-deposition. Erosion may have removed the layer after it was formed, while non-deposition indicates that the layer was never deposited in that particular location.
When eroded material mixes with a new rock layer deposited on top of it, this process is referred to as "conglomerate formation" or "sediment mixing." The eroded material, often called sediment or detritus, can become incorporated into the newer layer, leading to a composite of different rock types. This process is common in sedimentary environments where layers of rock are constantly being formed and eroded.
To determine whether the fault is older or younger than rock layer A, we can use the principle of cross-cutting relationships. If the fault cuts through rock layer A, it is younger than that layer, as it must have formed after the rock was deposited. Conversely, if rock layer A is found to be disrupted by the fault, then the fault is older. Therefore, examining the relationship between the fault and rock layer A is key to establishing their relative ages.
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.
