What is the purpose of the geologic time scale?

Answer 1

One purpose of the geological time scale is to support the idea of slow uniform processes such as Darwinian evolution.

Chales Lyell postulated that all of the earth's geological features could be explained by slow, uniform processes that are still in place today. For example, the Grand Canyon's current erosion process would require millions of years to erode the mile-deep gorge that it is today.

Lyell's theory of uniform process is supported by the geological time scale, which also provides ages for the different rock layers that the Grand Canyon's erosion has exposed.

Using Charles Lyell's theories to explain biological processes, Charles Darwin extrapolated minor adaptations and changes in the organisms he studied, and conjectured that these minor changes over eons of time might lead to the descent through modification of complex modern animals from a single "simple" cell.

The geological time scale is largely based on Darwin's theory of organic evolution. It supports Charles Darwin's theory of evolution by providing the vast periods of time required by the theory. It also dates the various rock layers using Darwin's theory of evolution, indicating that the layers with simpler fossils are older and the layers with complex fossils are younger.

Answer 2

The purpose of the geologic time scale is to categorize and chronologically organize Earth's history into distinct intervals, providing a framework for understanding the sequence of geological events and the evolution of life.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
