Final answer:
The rock layers from youngest to oldest relative ages are listed. Rock Layer H is older than Rock Layer M because it is located below it. The rock layers on the left side do not line up with the ones on the right side due to an unconformity. The event described in #3 occurred during the time of the unconformity.
Step-by-step explanation:
The rock layers from youngest to oldest relative ages are as follows:
- Rock Layer M
- Rock Layer L
- Rock Layer K
- Rock Layer J
- Rock Layer I
- Rock Layer H
- Rock Layer G
- Rock Layer F
- Rock Layer E
- Rock Layer D
- Rock Layer C
- Rock Layer B
- Rock Layer A
Rock Layer H is older than Rock Layer M because it is located below Rock Layer M in the rock layers. The Law of Superposition states that in layers of horizontal sedimentary rocks, the oldest rock layer is at the bottom and the youngest is at the top. Since Rock Layer H is below Rock Layer M, it is older.
The rock layers on the left side of the picture do not line up with the rock layers on the right side of the picture because of an unconformity. An unconformity is a gap in the geologic record due to erosion or non-deposition of sedimentary rocks. It represents a period of time when rock layers were not being formed.
The event described in #3 relatively occurred during the time of the unconformity. The unconformity represents a period of erosion or non-deposition of sedimentary rocks. The exact timeframe of the event cannot be determined without further information.
