Question

ordering 1 point strata puzzle 3 - order the events from oldest to youngest most recent - youngest 1 erosion 1 of limestone and granite. 2 erosion 2 of conglomerate. 3 deposition of conglomerate. 4 igneous intrusion. 5 granite intrusion of limestone and contact metamorphism. 6 deposition of limestone. 7 deposition of sandstone. order previous submit

Explanation:

Using relative geologic dating principles (superposition, cross-cutting relationships, contact metamorphism):

1. The oldest event is sediment deposition, starting with limestone.
2. An igneous intrusion (granite) cuts through the limestone, causing contact metamorphism, so this happens after limestone deposition.
3. Erosion wears down the granite and limestone surface next.
4. Conglomerate is deposited on the eroded surface, followed by another erosion event on the conglomerate.
5. Finally, sandstone is deposited on the eroded conglomerate surface as the youngest event.

Answer:

Oldest to Youngest:

1. Deposition of limestone
2. Granite intrusion of limestone and contact metamorphism.
3. Erosion 1 of limestone and granite.
4. Deposition of conglomerate.
5. Erosion 2 of conglomerate.
6. Deposition of sandstone.
7. Igneous intrusion.
