Question

units a, b, c, d, and e are sedimentary rock layers. the thick dark line is a fault, and the unit labeled \granite\ is an intrusion. questions 42 - 44 refer to this cross - section. question 43 (1 point) in the cross - section above, we know the fault is younger than layers e, d & c because of the principle of a) cross - cutting relations b) inclusions c) superposition

Explanation:

The principle of cross - cutting relations states that a fault or intrusion is younger than the rocks it cuts through. In the given cross - section, the fault cuts through layers C, D, and E, so the fault is younger based on this principle.

Answer:

A. cross - cutting relations
