Question

which happened first: d or e? how do you know? write your answer as complete sentences for full points (capital. period. proper spelling/grammar). copy/paste from the internet or use of ai is an automatic zero. recording can also be submitted. grading: 1/2 point = complete sentence 1/2 point = which happened first? (d or e) 1 point = explain how you know.

Explanation:

The principle of cross - cutting relationships in geology states that a fault or intrusion (in this case, D is an intrusion and E is a fault) is younger than the rocks it cuts through. D cuts through layers A, B, and C, and then E cuts through D and all the other layers. So D must have occurred first.

Answer:

D happened first. This is known because, according to the principle of cross - cutting relationships in geology, the fault E cuts through the intrusion D, meaning D must have been present before E formed.
