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 did scientist use when geologic timescale?
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 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 Geological Period preceded the Jurassic Period?
after Jurrasic period it is the Cretaceous period
What scientist studies rocks and geologic processes of ocean basins?
A scientist who studies rocks and geologic processes in ocean basins is a marine geologist. They investigate the formation and evolution of the ocean floor, as well as the geological features and processes that shape ocean basins. Their research contributes to our understanding of plate tectonics, seafloor spreading, and marine geology.
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 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 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.
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.

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 scientist worked with geologist to develop the geologic scale?
biologists
What does the geologic timescale encompass tens of millions or hundreds of millions of years?
More like over 4 billion years - that's the approximate age of planet Earth.
Will Earth die in 1 million years?
It is highly unlikely. A million years is a short time on a geologic timescale. Earth will remain habitable for a few hundred million years into the future.
How will a scientist make a geologic column of rock layers from different parts of the state?
