To understand the events in one region as compared to another, however, geologists have to stratigraphically correlate them before examining them.In order to accomplish this, geologists may use one of the concepts listed above: the Principle of Lateral Continuity or the Principle of Faunal Succession.
Walls in the Grand Canyon where rocks have not been disturbed are impressive examples of original horizontality.
Relative dating is a key component to unlocking the mysteries of the Earth's past.
Four principles of stratigraphy give geologists ways to understand rock layers, including when and how they were created.
The Grand Canyon acts as a modern testament to stratigraphy and relative dating.
Though radiometric dating offers a modern way to date rocks, the principles of stratigraphy remain a tried and true way to learn about rock layers.
Stratigraphy, or the scientific study of rock layers, includes relative dating.
When geologists study layers of rocks, they get a glimpse of the past.To understand stratigraphy and relative dating, four basic principles must be mastered.These concepts have also built scientists' perception of the Earth and its development since the beginning of time.The Principle of Lateral Continuity supposes that rock layers extend for some degree over the Earth's surface. In stratigraphy terms, this allows layers to be compared against each other.The Principle of Superimposition states that the oldest rocks will be at the bottom of all layers.These changes are consistent around the world, and allow geologists to determine what stratigraphic layers they might be examining by simply looking at fossils.
