The two correct methods of relative aging of rocks from your list are:
1. **Cross cutting relationships** - This principle states that if a geological feature cuts through another, the feature that has been cut is older.
2. **Superposition** - This principle states that in an undeformed sequence of sedimentary rocks, the oldest layers are at the bottom and the younger layers are at the top.
The other options, while relevant to geology, are either not specifically methods of relative dating or pertain more to absolute dating (like radiometric dating).
