Our transcription: Hutton also described a type of geologic structure called an "unconformity" in which one group of layers is truncated by another. He reasoned that unconformities form when strata are tilted, uplifted, and eroded, then buried by younger successions of strata. The presence of unconformities in many outcrops indicated to Hutton that the land was molded by repeated cycles of uplift and erosion. This idea was in profound conflict with the biblical view which held that the land had been created all at once.
