The diagram below shows a sequence of rock layers. Examine the diagram, and answer the question that follows. Using radiometric dating, scientists have determined that Layer M is 110 million years old. Based on this information and the principle of superposition: (1 point) Responses Layer T is younger than 110 million years, and Layers R, X, and G are older than 110 million years. Layer T is younger than 110 million years, and Layers R, X, and G are older than 110 million years. Layers T, R, X, and G are all younger than 110 million years. Layers T, R, X, and G are all younger than 110 million years. Layers T, R, X, and G are all older than 110 million years. Layers T, R, X, and G are all older than 110 million years. Layer T is older than 110 million years, and Layers R, X, and G are younger than 110 million years. Layer T is older than 110 million years, and Layers R, X, and G are younger than 110 million years.

Answer 1

Based on the principle of superposition, the geological layers are arranged with the oldest layers at the bottom and the youngest layers at the top. Since Layer M is determined to be 110 million years old and is likely situated in the middle or lower part of the sequence, it follows that Layer T, which is above Layer M, must be younger than 110 million years. Additionally, Layers R, X, and G, which are below Layer M, must all be older than 110 million years.

Therefore, the correct response is:

Layer T is younger than 110 million years, and Layers R, X, and G are older than 110 million years.
