Scientists use various methods such as radiometric dating, fossil evidence, stratigraphy, and biological markers to establish and categorize the different time divisions on the geologic time scale. These methods help in determining the age of rocks and fossils, as well as understanding the sequence of events that have occurred throughout Earth's history.

What information did scientist use when developing the geologic timescale?
Scientists used information from the fossil record, rock layers, radiometric dating, and other geological evidence to develop the geologic timescale. By studying these sources, scientists were able to divide Earth's history into distinct time periods based on major events and changes in the Earth's geology and life forms.
What sentence would use Geologic Timescale?
The Geologic Timescale is a system of chronological dating that organizes Earth's history into distinct periods marked by significant events or developments, such as the Jurassic Period or the Paleozoic Era.
What is the longest Eon in the Geologic Timescale?
The oldest eon of geologic time is the Archaean Eon of the Precambrian period. The oldest rocks and fossils date from this time, about 3.8 to 2.5 billion years ago. (Prior to that, the Hadean Eon began with the formation of the Earth. No geologic record exists from the Hadean, during which the Earth cooled from its molten state.)
What do scientists need know about geologic formations to make a geologic map?
To have a scientist make a geologic map, they need to know something about geologic formation to show what the map is meaning. They use color to show the differences of the kind of rock and its age.
What Geological Period preceded the Jurassic Period?
after Jurrasic period it is the Cretaceous period
What information did scientist use when developing the geologic timescale?

What is Geologic Timescale shown as a year?
The geologic timescale is represented as a calendar year for easier understanding of the vast span of time. In this representation, the Earth's formation occurs on January 1st and the present day occurs at midnight on December 31st. This compressed timescale helps to comprehend the timeline of Earth's history within a familiar context.
What sentence would use Geologic Timescale?
The Geologic Timescale is a system of chronological dating that organizes Earth's history into distinct periods marked by significant events or developments, such as the Jurassic Period or the Paleozoic Era.
What was the longest timeframe of the geologic timescale?
About 50 to 100 million years.
What does the geologic timescale encompass- tens of millions or hundreds of millions of years?
Hundreds of millions of years
What evidence do scientist use to place events on the geologic time scale?
they use major fossil records
Are mineral resources nonrenewable?
Mineral resources are considered non-renewable because their production by earth forces on a geologic timescale cannot keep up with their consumption by humans on a human timescale.
What types of evidence do scientist use in dividing geologic time into smaller time segments?
Iron precipitation is a chemical formula that scientists use in dividing geologic time into smaller time segments. They also use C14 dating to determine this.
What is the longest Eon in the Geologic Timescale?
The oldest eon of geologic time is the Archaean Eon of the Precambrian period. The oldest rocks and fossils date from this time, about 3.8 to 2.5 billion years ago. (Prior to that, the Hadean Eon began with the formation of the Earth. No geologic record exists from the Hadean, during which the Earth cooled from its molten state.)
Geologic Timescale plant and animal life during the Eoarchean Era?
the eoarchean era is a blah blah blah no one really cares hope this helps
What kind of clock does a paleontologist use?
A paleontologist might use a geologic timescale clock, which shows the Earth's history in a chronological order based on rock layers and fossil records. This allows them to track the evolution and extinction of species over millions of years.
What kind of scientist worked with geologist to develop the geologic scale?
biologists
