The granite cuts across the gneiss, what other principle allows you to distinguish the age relationship between the gneiss and the granite? a. law of superposition d. principle of inclusion b. law of original continuity e. faunal succession c. law of original horizontality

Answer 1

hello your question has some missing diagrams attached below is the missing diagram

1) Intrusive contact ( A )

2) Gneiss ( D )

3) Principle of Cross-cutting relationship ( D )

4) Principle of Inclusion ( D )

Step-by-step explanation:

1) The contact between the granite and the Gneiss represents an Intrusive contact

2) The oldest rock unit in the cross-section is Gneiss

3) The principle that allows for the distinguishing of the age relationship between Gneiss and Diorite is : Cross-cutting relationship

4) The principle that allows for the distinguishing of the age relationship between the Gneiss and the granite is : Principle of inclusion
