Firstly the rocks are weathered and eroded from an area above ground. Then, they are usually transported down to the sea via rivers. Once they are deposited in the sea, a lot of different layers pile up on top of each other on the sea bed. The Layers are then buried deeper and compacted, to form a sedimentary rock. Hope this helped :)
You should study sedimentary rocks when interpreting the sequence of bedrocks. Sedimentary rocks are formed by the accumulation and cementation of sediments over time, providing valuable information about the Earth's history and past environments through their layers.
They are called clastic sedimentary rocks.

No, sedimentary rocks formed from fragments of other rocks are called clastic sedimentary rocks. Chemical sedimentary rocks form from minerals that are dissolved in water and precipitate out to form rocks like limestone or halite.
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.

On top of the sequence, or closest to the surface. This is due to the principle of superposition, which states that in a sequence of undeformed sedimentary rocks, the youngest rocks are on top while the oldest rocks are at the bottom.

The law of superposition states that in an undisturbed sequence of sedimentary rocks, the youngest rocks are on top and the oldest are at the bottom. By observing the layers of sedimentary rock, geologists can determine the relative ages of the rocks based on their position in the sequence. The principle helps establish a chronological order of events in Earth's history.
The fundamental concept you are referring to is the Law of Superposition. It states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are found at the bottom, while the youngest rocks are found at the top.

False. Most sedimentary rocks cannot be directly dated by radiometric methods because they are composed of sediments that were already eroded and transported from existing rocks. Instead, geologists use relative dating techniques to determine the sequence of events in which sedimentary rocks were formed.
The sequences of sedimentary rocks in cratons are typically thin and are relatively undeformed or gently warped. The sequences in mountain belts, meanwhile, are thick and extensively folded and faulted.
