To determine the correct sequence of rock layers showing how the environment in the area changed over time, you usually need to consider principles of geology and sediment deposition. However, without the diagram you're referring to, I can provide general information based on common geological sequences:
- Ocean to Forest: This suggests an increase in land and vegetation due to the sea receding.
- Desert to Ocean: This would indicate a significant environmental change where dry land was submerged underwater.
- Forest to Desert: Suggests a drying out of the area, leading to less vegetation.
- Forests to Oceans: This would suggest that land was previously forested and then submerged.
Given these interpretations, it often follows that geological layers reflect time and transition of environments.
If we assume that the layer closest to the surface represents the most recent environment and the deeper layers represent older environments, you could choose the sequence based on what you expect the layers to indicate.
Given your choices, the sequence that typically fits a progression in environmental change could be A. Ocean → forest → desert, assuming that if the area was initially covered by water, it could have transitioned to a forested area and then into a desert through drying and climate change.
Without the visual reference, this is a reasoned analysis. If the diagram you are looking at indicates different transitions, another option may be correct.
