Unconformity

Real World Example

Imagine you've been writing a diary every day, but then you take a long break and skip several weeks. This gap in your diary is similar to an unconformity in geology, where there is a missing period in the rock record due to erosion or a lack of sediment deposition. Just as your diary has missing pages that disrupt the chronological flow of your entries, an unconformity represents a missing chapter in Earth's history, where the continuous layering of sedimentary rocks is interrupted.
