Relative dating provides information about the age and sequencing of geological events, rock layers, and fossils. It allows us to determine the relative order of events without assigning specific ages. This method is based on the principle of original horizontality, which states that sedimentary rocks are initially deposited horizontally. It also utilizes the principles of superposition, which states that in undisturbed rock layers, the oldest rocks are found at the bottom and the youngest are found at the top. With relative dating, we can establish the relative age of rocks, determine which layers are older or younger, and identify the occurrence of specific events, such as the presence of volcanic ash layers or the formation of unconformities.
