Answer:
The law of superimposition is used to determine the relative age of a rock layer. The correct option is:
Option D. the position of the layer compared to other layers.
Explanation:
The relative age of the rock layer can be determined by the law of superimposition. The relative age of a rock or mineral is determined by comparing the material that is younger or older with the surrounding. Generally, the oldest layer is at the bottom, whereas the youngest layer is at the top.
Reasons for incorrect answers:
- Option A. The thickness of the layer is dependent on several factors. The thickness of rock layers indicates whether the rock layer is stable or not.
- Option B. The rock layers can be composed of sedimentary or igneous rocks. The deposition and composition of different rock substances are different. Therefore, the composition cannot be used to determine the rock's relative age.
- Option C. The distance of the layer on the surface cannot be used to determine the relative age. The comparison between different rock layers is used to examine the age of the rock layers.
Therefore, the position of the layers compared to other layers in the surrounding is used to determine the relative age of the rock layer.
