Use the drawing to answer the question.
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.
Identify the principle geologists use to determine that layer E was not always tilted.
