Earth science relative dating
From its early formation to present, Earth has undergone extreme changes and evolved to be one of the most unique planets in our solar system.
Revisions to the relative time scale have occurred since the late 1700s.
It focuses on the worldwide coordinate system of latitude and longitude and applies that to more detailed topographic maps used by geologists and other earth scientists.
In this topic we look at the beginnings of astronomy and see how technology has allowed mankind to gain a better understanding of our Universe.
Think of relative time as physical subdivisions of the rock found in the Earth's stratigraphy, and absolute time as the measurements taken upon those to determine the actual time which has expired.
Absolute time measurements can be used to calibrate the relative time scale, producing an integrated geologic or "geochronologic" time scale.
We will focus on the heliocentric model and learn about how Earth fits into the Solar System, Galaxy and Universe.
