Intruding objects are younger in the law of inclusion.

Bottom layers of rock are younger only in the law of crosscutting.
Bottom layers of rock are younger only in the law of crosscutting.

Bottom layers of rock are older only in the law of crosscutting.

Answer 1

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

Intruding objects are younger in the law of inclusion.

Here's a brief explanation of both laws:

• Law of Inclusion: This law states that any rock fragments (inclusions) found within another rock must be older than the rock that contains them. Therefore, the inclusions are older.

• Law of Crosscutting Relationships: This law states that a geological feature (such as a fault or an igneous intrusion) that cuts through another feature must be younger than the feature it cuts.

So, in the context of the responses provided, the response about intruding objects being younger relates to the law of crosscutting, not the law of inclusion.
