Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free.
These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing.
Ice core sampling normally uses the assumption that the ring bands observed represents years.
One known example where this assumption was used is very misleading.
ANSWER: Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc.
This technique does not give specific ages to items.
Students take an informational tour to gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.
