DB-4: Dealing with time in geology
Knowing the time that geological events occur or when eras begin and end is as important to a geologist as a regular calendar is to us. Discuss the following:
1. What is meant by relative time in geology? When did the use of this term or concept begin, how is relative time determined and give some examples of relative time.

Dealing with Time in Geology
Relative time in geology refers to the physical subdivision of the rocks in the geology of the Earth, including the order and time of events they represent (Teed & Slattery, 2011). The relative time is determined in horizontal layers using relative age dating known as | PLACE YOUR ORDER NOW AT writtask.com | located below another one | PLACE YOUR ORDER NOW AT writtask.com | done based on the comparison, and through relative dating that uses a variety of techniques, which can be easily used when worked on by geologists in the field, and not a laboratory (Zalasiewicz et al., 2011).
In geology, numerical time involves the analogous difference between “lunchtime” and the relative time on a | PLACE YOUR ORDER NOW AT writtask.com | time involves a fossil or a rock, and radiometric dating methods based on natural radioactive decay such as carbon and | PLACE YOUR ORDER NOW AT writtask.com | time in geology is a concept that started during the Hadean | PLACE YOUR ORDER NOW AT writtask.com | geological structures whose numerical time has been determined include tectonics, syncline, faults, joints, and structural basin.
The history of the Earth is divided into different geological time chunks, and it dates back to the | PLACE YOUR ORDER NOW AT writtask.com | time was the method used by scientists to | PLACE YOUR ORDER NOW AT writtask.com | the sequence of events in the history of the | PLACE YOUR ORDER NOW AT writtask.com | time is used to subdivide the rocks and determine the time and order of events based on how they are | PLACE YOUR ORDER NOW AT writtask.com | is targeted at determining the amount of time taken to establish the ages of rock as part of the geological process (Zalasiewicz et al., 2011). Additionally, numerical time is used by scientists and geologists in Florida to establish the ages of metamorphic and igneous rocks that analyze their spontaneous decay.
