which of the following statements can be supported by the rock record to infer
earths history?
all listed choices.
tectonic uplift partially destroyed rock record.
layer a is the oldest stratum and contains the oldest fossils.

Explanation:

• Layer A is the oldest stratum and contains the oldest fossils: In sedimentary rock layers, generally, the lower - lying layers are older. Since layer A is at the bottom in multiple outcrops (Locations 1, 2, and 4), it is likely to be the oldest stratum.
• Tectonic uplift partially destroyed rock record: Location 3 has fewer rock layers compared to Locations 1, 2, and 4. Tectonic uplift can expose rocks to weathering and erosion, which can destroy parts of the rock record.
• Since both the statements about layer A and tectonic uplift are valid, "All listed choices" is also a valid option.

Answer:

All listed choices.
