Question

are \gaps\ in the rock record. they may have occurred from erosion of existing rock or non deposition of sediment (rock). these breaks (gaps) in the rock record represent times of significant geologic events that were not recorded by rock deposition.
lithosomes
breakages
unconformities
conformities

Explanation:

Unconformities are gaps in the rock record. They occur due to erosion of existing rock or non - deposition of sediment (rock). These breaks represent times of significant geologic events not recorded by rock deposition. Lithosomes are bodies of rock with specific lithology. Breakages is a general term for something being broken and not a specific geological term in this context. Conformities are the opposite of unconformities, representing continuous deposition.

Answer:

Unconformities
