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

Answer 1

Based on the principle of superposition, which states that in an undisturbed sequence of rock layers, the oldest layers are at the bottom and the youngest layers are at the top, we can analyze the age of Layers T, R, X, and G in relation to Layer M, which is 110 million years old.

If Layer M is 110 million years old and layers T, R, X, and G are below Layer M, then those layers must be older than 110 million years. Therefore, the correct response would be:

Layers T, R, X, and G are all older than 110 million years.
