## Step 1The problem is about the principles of sedimentary rock layering, also known as stratigraphy. The principle of superposition is a key concept in stratigraphy. This principle states that in an undisturbed sequence of sedimentary rocks, the youngest layer will be on top and the oldest on the bottom. This is because new layers of sediment are always deposited on top of older ones.## Step 2Given this principle, we can evaluate the options provided. Option A and B suggest that the age of the rocks can be determined by their weight or color. However, these are not accurate methods for determining the age of rocks. The weight and color of a rock do not provide information about its age.## Step 3Option D suggests that the layer that accumulated earlier will be deeper in the ground. This is not correct according to the principle of superposition. The principle of superposition states that the youngest layer will be on top and the oldest on the bottom.## Step 4Option C suggests that the layer that accumulated later will be deeper in the ground. This is correct according to the principle of superposition. As new layers of sediment are deposited, they accumulate on top of the older layers, making the younger layers deeper in the ground.
