How did scientists form the geologic time scale?
How is this scale organized?
What processes changed the Earth's environment during Precambrian time?

Answer 1

Answer:

Down below is what I had made after many different explanations and answers :)

Explanation:

  Scientists need to first understand that the laws of nature stay the same and have stayed the same for many years.  They formed the geologic scale by using important discoveries to understand and separate it into different sections based on what they found in those eras.  The largest intervals are eons being of millions of years.  Scientists studied fossils in rock that support that time period and record it, and order it with their estimated age of time.  

  The scale is organized by 4.6 billion years into time sections that are named with the fossils found for that time period.  During the Precambrian time the process of eroding the surface have lessened, there used to be meteors that used to hit the earth that survived the atmosphere, now the atmosphere is harsh enough to break down meteors with the rocks surrounding it and break down even further to small rocks when entering earth's atmosphere.

Answer 2

Scientists devised the geologic time scale after seeing variations in fossils as they moved from oldest to youngest sedimentary strata.

What is the geologic time scale?

The geologic time scale is a chronological dating technique used to classify geological layers' stratigraphy through time.

Scientists devised the geologic time scale after seeing variations in fossils as they moved from oldest to youngest sedimentary strata.

They employed relative dating to split Earth's past into time periods when comparable creatures were present.

The divisions of the geologic time scale are organized stratigraphically, with the oldest at the bottom and the youngest at the top.

GRI map abbreviations for each geologic time division are in parentheses. Boundary ages are millions of years ago.

The time scale was created by studying and observing strata of rock and their connections, as well as the times when various animals emerged, evolved,

Hence scientists devised the geologic time scale after seeing variations in fossils as they moved from oldest to youngest sedimentary strata.
