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. in the cross - section above, we know the granite intrusion is younger than the sedimentary rocks e and d because of the principle of (a) cross - cutting relations (b) inclusions (c) superposition (d) fossil succession

Explanation:

The principle of cross - cutting relations states that a geologic feature that cuts across another is younger than the feature it cuts. Here, the granite intrusion cuts across sedimentary rocks E and D, so it is younger based on this principle.

Answer:

A. cross - cutting relations
