However, his water-based hypothesis of the formation of rock strata was more than a wrong idea. Werner's theory was the first well-ordered geological description of the strata of Earth based on physical evidence that accounted for Earth's history. While his ideas were eventually overturned, often by his own students, he established a new way of thinking about the formation of Earth based on observation, experiment, and an attempt to understand historical geological processes.

Background

Earth's strata are the layers of various rock and mineral deposits that exist in a cross-section of Earth's crust. Strata look like the layers of a...
