A diagram shows a cutaway view of layers of rock. The top horizontal layer is labeled A. Under that layer is another horizontal layer labeled B. Layer D is under layer B and is tilted. Under that layer is layer E, which is also tilted. Under that layer is layer F, which is tilted. Under that layer is layer G, also tilted. Layer J appears under layer G. Layer I cuts horizontally through layers B, D, E, F, G, and J. A line labeled H cuts diagonally through layers A, B, E, F, and G.

A geologist examining a road cut at this location would recognize that Layer I is
younger, or older
than Fault H. This conclusion is made through the principle of
original horizontality, or cross-cutting relationships or superposition or uniformitarianiam

A geologist examining a road cut at this location would recognize that Layer I is younger than Fault H. This conclusion is made through the principle of cross-cutting relationships.
Cross-cutting relationships state that a geologic feature (such as a fault or an intrusion) that cuts through another feature must be younger than the feature it cuts through. In this case, since Layer I cuts through other layers and Fault H, it indicates that Layer I is younger.
