What else can I help you with?
What was the longest timeframe of the geologic timescale?
About 50 to 100 million years.
How are geologic units of similar ages shown on a geologic map?
Geologic units of similar ages are typically shown on a geologic map using the same color or pattern to represent them. This helps to visually differentiate between different units and understand their distribution across a region. Stratigraphic relationships and relative ages may also be indicated to show how these units are connected in terms of geologic time.
What sort of information are usually shown on a geologic map?
Where rocks outcrop or would outcrop if they could be seen.
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 are the guidelines used to determine the relative ages of the rocks and events shown by a geologic cross section?
The guidelines used to determine the relative ages of the rocks and events shown by a geologic cross-section is the Law of Superposition. It is the basic law of geochronology.
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.
How are geologic units of similar ages shown on a geologic map?
Geologic units of similar ages are typically shown on a geologic map using the same color or pattern to represent them. This helps to visually differentiate between different units and understand their distribution across a region. Stratigraphic relationships and relative ages may also be indicated to show how these units are connected in terms of geologic time.
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.
How geologic units of similar ages are shown on a geologic map?
on geologic maps, geologic units are distinguished by color. UNITS OF SIMILAR ARE ASSIGNED COLOR IN THE SAME COLOR FAMILY.

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 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.
How old are you in terms of Geologic time have you been born died yet or both?
The geologic timescale is very accurate and precise in the Holocene (started about 12000 years before today). Many dating methods applied for this period of time use calendar ages and are directly compatible with or easily converted into the Gregorian calendar. For example in terms of carbon-14 ages I was born in year 35 "in the future" (1950 is the reference year 0).
