Which law describes a layer of the Grand Canyon that is older than the layer above it? (1 point)
O law of superposition
• law of uniformitarianism
O law of inclusion
• law of crosscutting
The law that describes a layer of the Grand Canyon that is older than the layer above it is the law of superposition.
The law that describes a layer of the Grand Canyon that is older than the layer above it is the Law of Superposition.
The law that describes a layer of the Grand Canyon that is older than the layer above it is the law of superposition. This law is a fundamental principle in geology and states that in an undisturbed sequence of sedimentary rock layers, each layer is older than the layer above it and younger than the layer below it.
To find the answer to this question, you would need to understand the basic principles of relative dating in geology. The law of superposition is based on the observation that in an undisturbed sequence of rock layers, the older layers are deposited first, and subsequent layers are progressively younger. This can be visualized as stacks of pancakes, where the bottom pancake represents the oldest layer, and each subsequent pancake is younger.
In the context of the Grand Canyon, which is composed of layers of sedimentary rock, the law of superposition helps us determine the relative ages of the rock layers. By studying the different layers and their characteristics, geologists can establish the sequence in which the layers were deposited and infer their relative ages.
Therefore, the correct answer to the question is the "law of superposition."
