Understanding Strata And Stratum: Key Geological Terms

Strata and stratum are geological terms referring to layered rock formations. A stratum is a single layer, while strata is the plural form, referring to multiple layers. Stratum is the basic unit of sedimentary rock, formed by the accumulation of sediment particles over time. In contrast, strata is used to describe sequences of sedimentary rock layers that provide valuable insights into Earth's history and structure. Understanding the distinction between stratum and strata is crucial for comprehending geological processes and interpreting Earth's geological record.
