part a when did rock layer h form relative to the other rock layers? in your answers, compare layer h to as many rock layers as you can. space used(includes formatting): 451 / 3000 rock layer h is an igneous intrusion. it goes through layer e and all the layers beneath it, except layer j. so, layer h formed after layer e started to form and is younger than all the layers beneath it, with one exception. igneous intrusion j cuts through layer h, so layer j is younger than layer h. because the intrusion does not go through layer g, it formed before layer g. from the drawing, it cant be determined whether layer h is older or younger than layer a. part b what does l represent? when did it form?

Answer

Explanation:

Step1: Analyze rock - layer H

Rock layer H is an igneous intrusion. It passes through layer E and all layers beneath it except layer J. So it formed after layer E started to form and is younger than all layers beneath it (except J).

Step2: Consider layer J

Layer H does not cut through layer J, so layer J is younger than layer H.

Step3: Analyze layer G

The intrusion does not go through layer G completely. So layer H formed before layer G.

Step4: Analyze layer A

It's not clear from the drawing whether layer H is older or younger than layer A.

For part B:

Step1: Identify L

L represents a fault.

Step2: Determine its formation time

The fault cuts through layers A - E and the igneous intrusion H. So it formed after layer E, layer H and all the layers beneath them were in place.

Answer:

Part A: Rock layer H is an igneous intrusion. It formed after layer E started to form and is younger than all layers beneath it except layer J. It formed before layer G. It's indeterminate relative to layer A. Part B: L represents a fault. It formed after layer E, layer H and all the layers beneath them were in place.
