Which describes the difference between the law of inclusion and the law of crosscutting in relative dating of rocks and fossils? (1 point)

Question

• Intruding objects are younger in the law of inclusion.
• Bottom layers of rock are younger only in the law of crosscutting.
• Intruding objects are older in the law of inclusion.
• Bottom layers of rock are older only in the law of crosscutting.

Answer 1

The correct description between the law of inclusion and the law of crosscutting in relative dating of rocks and fossils is:

Intruding objects are older in the law of inclusion.

In relative dating, the law of inclusion states that any rock fragments (or inclusions) found within a layer of rock must be older than the layer itself. Conversely, the law of crosscutting states that a rock or fault that cuts across other rocks must be younger than the rocks it cuts through. Therefore, the other options provided are not accurate representations of these laws.
