Relative dating is the science of determining the relative order of past events i. In geology, rock or superficial deposits , fossils and lithologies can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating in the early 20th century, which provided a means of absolute dating , archaeologists and geologists used relative dating to determine ages of materials.
How does absolute dating help us to know how old a rock is?? 6. What radioactive isotopes are helpful for finding the ages of igneous rocks?
The Principle of Superposition tells us that deeper layers of rock are older than shallower layers Relative dating utilizes six fundamental principles to determine the relative age of a formation or event. This follows due to the fact that sedimentary rock is produced from the gradual accumulation of sediment on the surface. Therefore newer sediment is continually deposited on top of previously deposited or older sediment.
In other words, as sediment fills a depositional basins we would expect the upper most surface of the sediment to be parallel to the horizon. Subsequent layers would follow the same pattern. As sediment weathers and erodes from its source, and as long as it is does not encounter any physical barriers to its movement, the sediment will be deposited in all directions until it thins or fades into a different sediment type.
For purposes of relative dating this principle is used to identify faults and erosional features within the rock record.

In this two-hour special, renowned paleontologist Kirk Johnson takes us on an epic adventure through time at the polar extremes of our planet. Following a trail of strange fossils found in all the wrong places—beech trees in Antarctica, hippo-like mammals in the Arctic—Johnson uncovers the bizarre history of the poles, from miles-high ice sheets to warm polar forests teeming with life.
What caused such dramatic changes at the ends of the Earth? Premiered February 5, Yet hidden in these rocks, buried under the oceans and trapped in the ice, are clues that reveal a totally different past…. What powerful forces drove the poles to such extremes? This place is a dream. Think of all the other places you could be right now, then think about where you actually are. These icebergs are amazing. And they come in all sizes, from the size of little tiny ice cubes, all the way up to the size of mountains.
This stuff looks so solid, so vast, so permanent. How long did it take to form? And of course, how long will it last? If we could travel back in time, hundreds of millions of years, what would the Arctic and Antarctic look like?

Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy layers of rock are called strata. Relative dating does not provide actual numerical dates for the rocks. Next time you find a cliff or road cutting with lots of rock strata, try working out the age order using some simple principles:.
Fossils are important for working out the relative ages of sedimentary rocks. Throughout the history of life, different organisms have appeared, flourished and become extinct. Many of these organisms have left their remains as fossils in sedimentary rocks. Geologists have studied the order in which fossils appeared and disappeared through time and rocks. This study is called biostratigraphy.
