I WONDER - What Can We Learn From Sedimentary Rocks?

Sedimentary rocks provide insights into Earth's past. By examining rock layers, scientists can deduce past climates, environments, and the flora and fauna that existed. For instance, a rock layer rich in shells suggests a former shallow sea, while a sand-dominated layer indicates a past desert environment.
