using radiometric dating, scientists have determined that layer m is 110 million years old. based on this information and the principle of superposition (younger layers lie above older layers),\na. layer t is older than 110 million years, and layers r, x, and g are younger than 110 million years.\nb. layers t, r, x, and g are all older than 110 million years.\nc. layer t is younger than 110 million years, and layers r, x, and g are older than 110 million years.\nd. layers t, r, x, and g are all younger than 110 million years.

Answer

Explanation:

Step1: Recall superposition principle

Younger layers are above older layers.

Step2: Analyze layer M age

Layer M is 110 million years old. Layer T is below M, so it is older. Layers R, X, G are above M, so they are younger.

Answer:

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