Question

He principle of cross-cutting relationships states that a fault or

trusion is younger than the rocks that it cuts through. The fault (E)
uts through all three sedimentary rock layers (A, B, and C) and also
me intrusion (D). So the fault must be the youngest feature. The
trusion (D) cuts through the three sedimentary rock layers, so it must
e younger than those layers. By the law of superposition, C is the
Idest sedimentary rock, B is younger and A is still younger.
he full sequence of events in:
1. Layer C formed.
2. Layer B formed.
3. Layer A formed.
4. After layers A-B-C were present, intrusion D cut across all three.
5. Fault E formed, shifting rocks A through C and intrusion D.
6. Weathering and erosion created a layer of soil on top of layer A.

Answer 1

Layer 4 occurred after layers A, B, C, intrusion D, and fault E. The principle of cross-cutting relationships teaches that a fault or intrusion is younger than the rocks it cuts through.

Step-by-step explanation:

The full sequence of events in the given diagram from oldest to youngest is:

1. Layer C formed;
2. Layer B formed;
3. Layer A formed;
4. After layers A-B-C were present, intrusion D cut across all three;
5. Fault E formed, shifting rocks A through C and intrusion D;
6. Weathering and erosion created a layer of soil on top of layer A.

Layer 4 in the diagram occurred after layers A, B, C, intrusion D, and fault E were already present. This can be determined by observing that layer 4 is located above all the other layers and intrusions, indicating that it is the youngest layer.

The principle of cross-cutting relationships teaches that a fault or intrusion is younger than the rocks it cuts through. In the given diagram, the fault (E) cuts through all three sedimentary rock layers (A, B, and C) and the intrusion (D), so the fault must be the youngest feature. This principle is used to determine the relative ages of different geological events and formations.
